Abstract:
PURPOSE:To specify the rotating direction of a rotor by providing a hole at an intermediate plate engaged with one end of a rotor shaft, slidably inserting a pin into the hole of the plate, and arranging a cam plate having the prescribed annular groove at both sides of the plate. CONSTITUTION:Cam plates 5, 6 are secured to a cover 3 of a bracket assembly, and an intermediate plate 4 engaged with one end of a rotor shaft 13 is rotatably disposed between the plates 5 and 6. A hole 10 is formed in a thrust direction between the center and the outer periphery of the plate 4, a pin 9 is slidably inserted into the hole 10, a circumferential groove having a taper to slide the pin 9 while moving in the thrust direction upon rotation of the shaft 13 is formed at each of the plates 5, 6, and a stopper wall 12 with which the pin 9 is contacted with the groove of at least one cam plate such as the plate 5 in reverse rotation, is formed.
