Elastic member for attaching sensor device and sensor using the same

摘要

An elastic member attaches a sensor device having a sensor protrusion portion into a through hole of a sensor attachment member in such a manner that the elastic member is temporarily assembled onto the sensor protrusion portion and inserted together with the sensor protrusion portion into the through hole. The elastic member includes a hollow portion and a rear end portion having a rear end flange and a bead portion. The rear end flange protrudes from an outer circumferential surface of the rear end portion for locking on a peripheral portion of one end of the through hole. The bead portion is elastically deformable and protrudes from either or both of one surface of the rear end flange facing the sensor device and the other surface of the rear end flange facing the sensor attachment member.
