A power transmission device includes: a planetary gear mechanism including a sun gear that is an external tooth gear, a ring gear that is an internal tooth gear located coaxially with the sun gear, a pinion gear that is an external tooth gear and meshes with the sun gear and the ring gear, and a carrier that rotatably supports the pinion gear; a case member that accommodates the planetary gear mechanism; an extending member that extends from an outer peripheral portion of the ring gear toward one side in a thrust direction; and a holding member that is provided at an end of the extending member on a side opposite to the ring gear side in the thrust direction, the holding member being connected to the case member for holding the ring gear.

Power transmission device

A fuel supply device includes a flange unit and a pump unit. The flange unit includes a flange main body for closing an opening formed in an upper wall of a fuel tank. The pump unit includes a joint member that is connected to the flange main body so that both components may be movable relative to each other in the vertical direction. The interval in the vertical direction between the flange main body and the joint member is restricted from going below a minimum vertical interval. The minimum interval occurs when a stand-off portion provided as part of the flange main body and a connecting plate portion provided as part of the joint member come into mutual contact with each other and abut each other in the vertical direction.

Fuel supply device

When a fuel tank is inclined at a negative slope and tilted to the right side, it may be tilted such that a position of a mesh member is relatively higher than a position of a vapor outlet of a vapor outlet passage. In this case, air may enter into a leak passage from an outlet port such that interfacial tension is generated in the mesh member. The interface between fuel and air is present at the mesh member, and the interfacial tension generated at the interface serves to prevent air from entering into a discharge pipe.

A flange main body as a cover member for a fuel tank includes a cover plate for closing an opening of the fuel tank, an accommodating tubular portion formed as part of the cover plate so as to extend through the plate in a plate thickness direction, and a rib formed at the cover plate. The accommodating tubular portion and the rib are formed to be non-contiguous.

Cover member for fuel tank

A fuel supply device includes a flange unit configured to be attached to an upper wall of a fuel tank to close an opening of the fuel tank, a pump unit configured to be disposed within the fuel tank, and a coupling mechanism moveably coupling the pump unit to the flange unit in a vertically slidable manner. The coupling mechanism includes a fixed-side rail member having a rail portion extending vertically from the flange unit, and a movable-side rail member having a channel-groove shaped rail groove extending from the pump unit. The channel-groove shaped rail groove is slidably engaged with the rail portion of the fixed-side rail member. A recess having a semi-circular cross section is formed at a corner of the rail groove of the movable-side rail member.

A powertrain unit includes an engine and a power transmission device that transmits drive force of the engine to a drive wheel of a vehicle, the power transmission device including a transmission provided in a power transmission path between the engine and the drive wheel. An oil pan is provided below the transmission. A guard member covering at least a portion of the oil pan from below is provided below the oil pan. The guard member has a first end secured to a portion of the powertrain unit which is located in front of the transmission in a vehicle longitudinal direction, and has a second end, opposite the first end, secured to a portion of the powertrain unit which is located behind the transmission in the vehicle longitudinal direction. The rigidity of the powertrain unit is improved by utilizing the rigidity of the guard member.

Powertrain unit

A vehicle front structure includes a roof header, which is arranged on a lower side of a front part of a roof panel of a vehicle in a longitudinal direction of the vehicle, and extends in a vehicle width direction, and a rear wall part, which is provided in the roof header, and extends towards the roof panel on the rear side of the roof header. The roof header is provided with a region in which a length of the roof header in a front-rear direction of the vehicle is longer than that of a surrounding area, and height of the rear wall part is smaller than that of the surrounding area.

Vehicle front structure

An AI pipe () is formed with a first housing () and a second housing (). The first housing () is made from a thin metal sheet and has a clamp portion (C) that was left remaining. The second housing () is also made of a thin metal sheet and also has a clamp portion (C) that was left remaining. When fitted together, the first housing () and the second housing () form a pipe portion (). With this AI pipe (), a through-hole (H) which is punched out by press working is formed in at least one of the clamping portion (C) and the clamping portion (C).

Vehicle component and engine component for supplying secondary air

An oil pan () includes: a pair of oil pan rail portions (), which are spaced apart from each other under an engine body (), and are fastened to the engine body (); a pair of side wall portions (), facing each other, which are formed integrally with the oil pan rail portions (); and a cylindrical portion (), which surrounds a driving axle (L,R) passed through the oil pan (), and is integrally joined with the pair of side wall portions () near the pair of oil pan rail portions (). At least one axial end () of the cylindrical portion (), an upper half portion () of the cylindrical portion () positioned over the driving axle (L,R) is thickened upward up to the level near the upper surface of the oil pan rail portion ().
