To provide a side stand switch that is able to appropriately prevent coming-off of a sealing member without excessively increasing a manufacturing load.SOLUTION: A side stand switch includes: a rotor portion having a rotating body that rotates in conjunction with a side stand; a case portion having a through-hole through which the rotating body is inserted; a sealing member having a cylindrical body composed of a rigid member extended in a rotating-shaft direction of the rotating body and a sealing portion fixed to the cylindrical body and composed of an elastic member, wherein the sealing member is disposed between the rotating body and the through-hole by being press-fitted. In the side stand switch, the sealing portion has a first elastic portion that is formed with a thickness equal to that of an outer side of the cylindrical body and that is in firm contact with an inner peripheral surface of the through-hole, and a second elastic portion that is provided on an inner side of the cylindrical body and slidably opposite to an outer peripheral surface of the rotating body, the inner peripheral surface of the through-hole has, at a position opposite to the cylindrical body, an airtight portion and a coming-off prevention portion located further inside the case portion than the airtight portion, the first elastic portion disposed opposite to the airtight portion is compressed in an airtight manner, and the through-hole increases in diameter in the coming-off prevention portion.SELECTED DRAWING: Figure 4

    【課題】製造上の負荷を過度に高めることなくシール部材の抜け止めを適切に実現可能なサイドスタンドスイッチを提供する。【解決手段】サイドスタンドに連動して回動する回転体を有するロータ部と、回転体が挿通する貫通孔を有するケース部と、回転体の回転軸方向に延設された剛性部材からなる筒状体と筒状体に固定され弾性部材からなるシール部とを有するシール部材と、を備え、シール部材が回転体と貫通孔との間に圧入により配置されたサイドスタンドスイッチであって、シール部は、筒状体の外側に等しい厚さで形成されて貫通孔の内周面に圧接する第1弾性部と、筒状体の内側に設けられて回転体の外周面に対して摺動可能に対向する第2弾性部と、を備え、貫通孔の内周面は、筒状体に対向する位置に、気密部と、気密部よりもケース部の内側に位置する抜け止め部と、を有し、気密部に対向配置される第1弾性部は気密可能に圧縮され、抜け止め部において貫通孔は拡径する。【選択図】図4
