A lever operation device includes an operation lever which rotates integrally with a steering wheel of a vehicle and receives operations at least in upward and downward directions and around which a predetermined region is set so as to prevent the operation lever from contacting with a leg of a user seated in a driver's seat when the steering wheel is rotated to a maximum steering angle, and an operation portion that is arranged on the operation lever so as not to be located out of the region and includes plural operating positions each assigned an executable function.

Lever operation device

A switch device includes a switch body, which is attached to and rotated integrally with an irregularly-shaped steering unit, and a lever unit, which is held pivotally about a switch body. The lever unit includes a lever shaft including a base, which extends in a direction intersecting the steering shaft, and an arm, which is formed integrally with the base and extends in a direction that differs from the direction in which the base extends. The lever unit also includes a lever head at the distal end of the lever shaft, and the lever head extends from the lever shaft in the width direction, which intersects an axial direction.

Switch device

A switch device includes a switch body, which is arranged at the back side of a steering unit, and a lever unit, which is attached to the switch body to allow for switching by a pivotal operation about a first axis, which extends in the axial direction of a steering shaft. The lever unit includes a lever shaft, which extends in a direction intersecting the first axis of the pivotal operation, a lever head, which is arranged at the distal end of the lever shaft and has a larger dimension than the diameter of the lever shaft, and a push operation unit, which allows for switching by a push operation. The push operation unit is arranged so that the operation direction of the push operation is directed toward the first axis.

Looseness of a rotary connector and lifting of the rotary connector which occurs depending on a harness wiring state are prevented, to reduce inconvenience such as generation of an abnormal sound due to the rotary connector contacting a steering wheel. In a fixing structure of a rotary connector, which includes a projecting pieceto fix the rotary connector to a combination switch and a locked portionto be locked by the projecting pieceand in which a laterally protruding locking clawis formed in a tip portion of the projecting piece, the locking clawof the projecting pieceis integrally provided with a flexible urging portionthat displaces and urges the locking clawin a locking direction. A contact surfaceis formed on the locking claw, the contact surfaceobliquely coming into contact with a locking side cornerof the locked portionfrom the opposing side.

Rotary connector and fixing structure of rotary connector

A rotational movement detection device includes a rotating member including a through hole passing therethrough from a first surface to a second surface opposite the first surface, the rotating member rotating around the through hole to generate a magnetic field around the rotating member, a rotation angle detection part that detects a rotation angle of the rotating member, a movement detection part that detects a movement along a rotational axis of the rotating member, and a holding part including a guide part and an arrangement part formed integrally therein, the guide part being inserted into the through hole to guide the rotation of the rotating member and to hold the rotating member, the arrangement part having thereon the movement detection part arranged facing a side surface of the rotating member.

Rotational movement detection device

A switch device includes a switch body that supports a lever operating portion, and a cylindrical fitting portion through which the switch body is attached to an attached portion. The fitting portion includes a plurality of elastic deformation portions elastically deformable by a clamping force of a clamping band member and a pressed-bulging portion bulging from an outer surface of a tip portion of the elastic deformation portions. The pressed-bulging portion is configured to locate at a contact position with the attached portion.
