Japanese Patent JP7367654
Kind Code:
B2
Abstract:
In a torque sensor (1), a sleeve (21) is an annular member mounted on a first rotating member. An intermediate member (26) is an annular member placed on an outer circumferential face of the sleeve (21). A magnet (25) is an annular member placed on an outer circumferential face of the intermediate member (26). A yoke (35) is mounted on a second rotating member and faces the magnet (25) in a radial direction. A rotating member connecting part (211) of the sleeve (21) is cylindrical and is in contact with the first rotating member. An intermediate member connecting part (215) is at a position shifted with respect to the rotating member connecting part (211) in an axial direction parallel to a central axis Z. An outer diameter (E219) of a sleeve end (219), which is an end of the intermediate member connecting part (215) opposite from the rotating member connecting part (211), is smaller than a minimum inner diameter (I25) of the magnet (25).
