Abstract
A switch device includes a switch body and an operation member. The switch body includes a case and a rotary shaft rotatably supported by the case and extending from one end of the case in an axial direction. The operation member is joined to the rotary shaft. The case has a cylindrical outer surface and the operation member has a cylindrical inner surface disposed coaxial with the cylindrical outer surface of the case. A support member is disposed at one of the cylindrical outer surface of the case and the cylindrical inner surface of the operation member and has an edge portion extending linearly along a circumferential direction of the one of the cylindrical outer surface and the cylindrical inner surface, so that the edge portion can slidably contact the other of the cylindrical outer surface of the case and the cylindrical inner surface of the operation member.
