Disclosed is a sensor that can accurately detect displacement and prevents the phenomenon of a contact section between a shaft member and a sliding element receiver being shifted. The sensor comprising: a case having a through hole; a resistance substrate fixed at an inside of said case; a shaft member having a first end portion which is one end of the shaft member placed within said case and a second end portion which is other end of the shaft member exposed to an outside of said case from said through hole, said shaft member being placed at said through hole in a movable manner in an axial direction; and a sliding element receiver having a bearing end contacting with said second end portion of said shaft member, and attached with a brush sliding together with said resistance substrate, said sliding element receiver being capable of moving relatively against said resistance substrate with said shaft member. A hemispherical end face is formed at said first end portion. A hemispherical hole internally contacting with said hemispherical end face is formed at said bearing end. |
