<p>PURPOSE:To facilitate assembly by forming a cylindrical body part which covers the outer peripheral face of a rotor on a drive coupling plate for transmitting the rotation of a driving shaft to said rotor, forming a fitting groove which is opened in the axial direction on said body part, and axially movably housing a shoe member in said fitting groove. CONSTITUTION:Since a fitting groove 31 for preventing the separation of a shoe member 25 is formed on a drive coupling plate 9, it is not necessary to form a fitting groove on a rotor 7 which is made of a hard material, and the drive coupling plate 9 can be formed with a relatively soft material facilitating machining. Further, since the fitting groove 31 is opened in the axial direction of the plate 9, this plate 9 can be lastly inserted in between the rotor 7 and a rotary ring 4 at the time of assembling. And, the assembly of the shoe member 25 can be carried out in a stage when the plate 9 does not exist between the rotor 7 and the rotary ring 4 providing a space between the rotor 7 and the rotary ring 4, to facilitate the assembly of the shoe member 25.</p> |
