ROTATION ANGLE DETECTING DEVICE

摘要

A rotation angle detecting device, provided with a magnet member (20) placed in a shaft member (2) to face a magneto-electric conversion element (10) and detecting a rotation angle of the shaft member in response to a relative rotation of the magnet member with respect to the magneto-electric conversion element, includes: a housing (1) accommodating the magneto-electric conversion element; a supporting member (3) connected to the housing and rotatably supporting the shaft member; and a connector member (5) electrically connected to the magneto-electric conversion element, wherein the housing includes a main body portion (1 a) where an element chamber (SC) accommodating at least the magneto-electric conversion element is formed and a joint (1 b) integrally formed with the main body portion and connected to the connector member, and the connector member is fitted into and connected to the joint in a liquid-tight manner.
