A steering damper device for a saddle riding vehicle includes a tubular damper including a cylindrical damper cylinder and a piston rod slidably passed through the damper cylinder. Either the damper cylinder or the piston rod is supported on an upper frame or a down frame of the saddle riding vehicle. The upper frame extends rearwardly from a head pipe through which a steering shaft passes and which holds the steering shaft therein rotatably about an axis thereof. The down frame extends downwardly from the head pipe. The steering shaft rotates with a bottom bridge. The tubular damper is disposed such that an axis thereof is disposed on a vehicle width direction central plane. The tubular damper extends or contracts as the bottom bridge rotates. The tubular damper extends or contracts within a space between the upper frame and the down frames in a side view.

A vehicle shock absorber includes a plurality of communication holes axially provided side by side in a peripheral wall of the cylinder of the damper, another communication hole provided in a peripheral wall of the cylinder and located below a position of piston of the damper, and a third oil chamber provided in an outer tube and an inner tube of a fork body and outside the cylinder and communicating with only a second oil chamber via the communication holes. This configuration enables the vehicle shock absorber to make a damping force generated by the damper positional dependent, and suppresses the entering of an air bubble into the cylinder, even when a cylinder of the damper is located above an oil level in an oil reservoir within the absorber body.

A chain guide device wherein it is unnecessary to make a chain guide body a thick and heavy member to enhance the productivity of the chain guide body. The chain guide body is split into a left guide half having a left-side upper split surface and a left-side lower split surface which are formed along a longitudinal direction of a chain and a right guide half having a right-side upper split surface and a right-side lower split surface. The guide bodies, which are roughly U-shaped, can be easily demolded after injection molding to enhance productivity. The contact of the chain with the split surfaces is lessened, as compared with the case where split surfaces are inclined at an angle relative to the longitudinal direction of the chain. Accordingly, wearing of the split surfaces is restrained, and it is unnecessary to make the chain guide body greater in thickness and weight.

A pair of left and right arm portions integrally formed by molding with a pivot portion formed on front ends and an axle support portion formed on rear ends. An opening portion with a peripheral portion endlessly contiguously formed by a pivot portion that connects front ends of both arm portions, a cross portion and both arm portions. A pair of left and right indented recessed portions is formed on an inner surface of a wall having support bosses projecting out of a lower surface of the wall. A pair of left and right reinforcing ribs that is positioned outside both recessed portions in the vehicle widthwise direction are integrally formed on the inner surface of the wall on which the support bosses is formed in a projecting manner toward the inside of the cross portion.

Swing arm for miniaturized vehicle

A steering apparatus for a vehicle includes a stem pipe disposed in a head pipe by upper and lower bearings interposed therebetween, a seal member for covering the upper bearing, and bottom and top bridges mounted on lower and upper ends of the stem pipe, respectively. A single fastening bolt, having a step formed between a head and a threaded surface thereof, is fitted in a pipe insertion hole of the top bridge and the upper threaded portion of the stem pipe. The stem pipe is firmly tightened and supported by a stem pipe slot-tightening mechanism of the top bridge. The fastening bolt is tightened by only a tightening force required to keep the fastening bolt from loosening. Also, a number of components required for the inventive steering apparatus is reduced, since an additional component, previously used for preventing loosening of a fastening bolt, is made unnecessary.

A front fork for easily optimizing an oil quantity in a damper cylinder with a relatively simple structure without affecting operability of a free piston even in an assembled state. An escape portion is formed on an outer periphery of a piston rod at a position where a seal member mounted on a sealing cap faces in an opposed manner when a front fork extends to the maximum.

A steering damper ensures a wide longitudinal illumination range of a road surface when a light unit is provided and facilitates layout of parts and simplifies structure without degrading appearance. A steering damper mounting structure is provided for a vehicle, which includes a head pipe, a front fork, a fork bridge, and a steering damper. The steering damper is mounted on the fork bridge and the head pipe. The steering damper dampens a movement transmitted from a side of the front wheel to a handlebar. In this steering damper mounting structure, the steering damper is mounted to the head pipe and the top bridge and disposed on the side of the top bridge between the top bridge and the bottom bridge. Additionally, a light unit is disposed on the side of the bottom bridge between the top bridge and the bottom bridge.

A vehicle number plate that allows a steering damper to be disposed without impairing the functions of the number plate, and is less susceptible to an effect of cross wind. The vehicle includes a front fork, which suspends a front wheel, disposed steerably on a head pipe on a vehicle body and a steering mechanism including a handlebar mounted on the front fork. The number plate is marked with a competition identification number and is disposed at a front portion of a fork bridge including a top bridge and a bottom bridge to connect left- and right-hand portions of the front fork. In the vehicle, the steering damper is disposed between the head pipe and the bottom bridge. The number plate includes a protruded portion that protrudes forwardly at a center thereof and narrows toward a lower portion, the lower portion covering an area forward of the steering damper.

A steering damper mounting structure of a vehicle includes a head pipe, a front fork, a fork bridge, and a steering damper. The front fork, which suspends a front wheel, is steerably disposed on the head pipe. The fork bridge connects left and right members of the front fork. The steering damper is mounted on the fork bridge and the head pipe. The steering damper dampens a steering directional movement transmitted from a road surface to a handlebar via the front wheel and the front fork. A lower mounting portion on a side of the head pipe is disposed on a side of an axis as a center of pivotal motion of the front fork relative to the fork bridge, more specifically, an upper mounting portion on a side of the top bridge. The resulting configuration reduces the size of a front portion of a vehicle and a steering damper.

Steering damper mounting structure for vehicle

Vehicle apparatus for a vehicle including a chain guide device which can be easily mounted to the vehicle with a reduced number of parts. The chain, guide device for guiding a chain in the vehicle includes a main frame and a rear swing arm extending rearward from the main frame. The chain guide device also includes a stay extending downward from the rear swing arm, a sectionally U-shaped plate member fastened to the stay using fastening members, and a chain guide member mounted in the plate member. The chain guide member has a chain guide hole through which the chain passes through to be guided. The chain guide member is fixed by fitting the lower surface and the right and left side surfaces of the chain guide member to the plate member and by fitting the upper surface of the chain guide member to the stay.
