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 combination switch lever includes a cylinder body including an opening, a plurality of switches to operate an electric component disposed in the vehicle, a flexible board that is disposed inside the cylinder body and that includes a circuit part and a non-circuit part disposed outside the circuit part in a width direction, and a first guide member and a second guide member that are disposed inside the cylinder body so as to be opposite to each other sandwiching the flexible board. An inside projection is formed at a vicinity of the opening of the cylinder body on an opposite surface of the first guide member and/or the second guide member, and the inside projection presses the non-circuit part. The first guide member and the second guide member include an adjacent opposite surface such that an opposite distance therebetween is partially narrowed.

Combination switch lever

A switch device includes a cylindrical movable lever-portion that is operable in multiple directions, a unit case that supports the movable lever-portion, and a flexible printed circuit board routed from an inside of the movable lever-portion to an inside of the unit case. A routed portion of the flexible printed circuit board to be routed inside the unit case includes a stress absorber configured to absorb a stress applied to the flexible printed circuit board. The stress absorber includes a plurality of curved portions curved in opposite directions to each other.

Switch device

A subassembly includes an intermediate knob serving as a first knob rotatably fitted to and supported by a middle serving as a fixing portion, a first spring and a first ball for giving a detent feeling upon a rotary movement between the middle serving as the fixing portion and the intermediate knob, a distal end knob serving as a second knob rotatably fitted to and supported by the middle serving as the fixing portion, and a second spring and a second ball for giving a detent feeling upon a rotary movement between the middle serving as the fixing portion and the distal end knob. In such a subassembly, the intermediate knob, the first spring and the first ball, and the distal end knob, the second spring and the second ball are integrally assembled as a subassembly.

Provided is a switch device including rotor members mounted so as to be rotatable about a longitudinal axis of a lever main body, knob members mounted so as to be integrally rotatable with the rotor members, the knob members including cam surfaces that face the cam surfaces of the rotor members with a gap therebetween, a movable contact member being movable in the longitudinal axis direction by a rotational operation of the rotor members and the knob members about the longitudinal axis, and a flexible substrate linearly disposed in the longitudinal axis direction in at least a movable range of the movable contact member, the flexible substrate including a contact portion, a contact terminal of the movable contact member being brought into contact with and separated from the contact portion in association with the movement in the longitudinal axis direction of the movable contact member.

A switch device includes a knob member rotatably fitted to and supported by a middle serving as a fixing portion, and a rotor member integrally mounted to the knob member and rotatably supported by the middle. A rotation regulating portion that regulates a rotatable range of the knob member with respect to the middle and rotation sliding surfaces in a rotational axis direction of the middle and the knob member are collectively formed.
