Abstract

PURPOSE:To prevent friction between a wave washer and a housing in a sensor construction which is adapted to preclude the spinning of a rotating shaft of a sensor using the washer, by arranging the washer so as not to press or slide against the housing. CONSTITUTION:A bush 5 is fitted securely into a stepped small-dia. part 33 of a rotating shaft 3 of a sensor and a magnet 6 and a washer 7 are provided on the circumference of the fitted part in such a manner as to be movable in the direction of thrust while being retained in the direction of rotation. A wave washer 8 is provided between the bush 5 and the magnet 6 and a thrust load is applied to the washer 7 to press the washer 7 on a housing 2. This prevents the spinning of the rotating shaft 3 otherwise caused by vibration with the rotation of an engine during the stoppage of a vehicle. The wave washer 8 turns together with the bush 5, the magnet 6, the washer 7 and the rotating shaft 3, not directly pressing and sliding against the housing 2, thereby preventing friction therebetween.
