<p><P>PROBLEM TO BE SOLVED: To improve workability of both fitting and preventing the rotation of an electromagnet. <P>SOLUTION: This coupling comprises a clutch 49 arranged between torque transmission members 45, 47, the electromagnet 61 for moving an armature from the outside of the member 45 to connect the clutch 51 thereto, a cam 55 to be operated by receiving transmission torque between the members 45, 47 when the clutch 51 is connected thereto, to connect a clutch 49 thereto, and a stationary side casing 37 storing these. The member 45 is supported at its outer peripheral face on the inner peripheral face of a core 99 of the electromagnet 61 via a bearing 113. The core 99 is fitted at its fitted portion 101 to the casing 37 and centered, and the rotation of the core 99 relative to the casing 37 is prevented by a rotation preventing means 183. The rotation preventing means 183 is provided near the fitted portion 101. The bearing 113 is provided on the axial end side of the torque transmission member 45 beyond a recessed portion 153 of a rotor 67 into which the core 99 is fitted. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
