A first virtual rotational axis exists at a position separated from the position of a first virtual line which passes through a path through which the cancel lever is advanced and retracted (in the longitudinal direction of an elongated guide hole). A first engaging portion of the cancel lever is line symmetric about a second virtual line which connects the first virtual rotational axis of a cancel cam member and a second virtual rotational axis of the cancel lever.

Input operating apparatus

A holder incorporated in and fixed to cylindrical lever body rotatably supports a rotating knob, and the rotating knob supports a pressing knob so as to be able to reciprocate in the axial direction. Any of these cylindrical lever body, the rotating knob and the pressing knob has a non-circular outline along an orthogonal plane which is orthogonal to the axial direction. The rotating knob is arranged in the vicinity of the distal end of the cylindrical lever body, and the rotating knob opposes a main surface of a circuit board mounted on the holder. The main surface of the circuit board includes a push switch having a contact pattern which can be connected to and disconnected from a slider attached to the rotating knob, and a driven part thrust by a drive rod of the pressing knob during a pressing operation.

In-vehicle lever switch device

In a lever switch device, a holder is assembled in and fixed to a cylindrical lever body formed by combining halved lever bodies and the holder supports two rotating knobs so as to allow the rotating knobs to rotate. Further, a circuit board is mounted on the holder, and both main surfaces of the circuit board face the rotating knobs, respectively. The rotating knob is exposed to the outside at the end of the cylindrical lever body in the axial direction, and the rotating knob is exposed to the outside through window portions formed at the cylindrical lever body. Sliders are mounted on the rotating knobs, respectively, one slider can come into contact with and be separated from contact patterns formed on the main surface, and the other slider can come into contact with and be separated from contact patterns formed on the main surface.

A turn signal switch device includes an operation lever, a holding member configured to support a base portion of the operation lever and to be turnable together with the operation lever, a housing configured to support the holding member such that the holding member is turnable, a cancel lever provided in the housing and configured to be advanceable, retractable, and turnable along with the turning of the holding member, and a cam member provided in the housing and facing the base portion of the operation lever. The housing holds a third elastic member configured to elastically urge the cancel lever toward a turning locus of a cancel projection. The third elastic member is a coil spring.

Turn signal switch device

A turn signal switch device comprises a control lever that has a lever portion that projects from a base portion that has a shaft hole, and a shaft that has a head disposed at one end. The head has a larger diameter than that of the other portion of the shaft, and is inserted into the shaft hole so as to serve as a rotating shaft of the control lever. The device also comprises a holder that is formed of synthetic resin, has an opening into which the base portion is inserted, and supports the shaft such that the control lever can be tilted along one plane. The device further comprises a case that supports the holder such that the control lever and the holder can be integrally tilted along the other plane which substantially crosses the one plane at right angles. A ring-shaped concave groove that extends in a circumferential direction is provided at the other end of the shaft. A bearing hole with a smaller diameter than that of the head and into which the shaft is inserted is provided in a pair of side plates of the holder that faces each other. A flexible engagement piece that extends inwardly in a radial direction of the bearing hole so as to be engaged with the ring-shaped groove is provided in one of the pair of side plates.
