PURPOSE:To unify both sucking parts without separating in a rotating direction and a shaft direction without fail by constituting a sucking part of a resin-made hub member and a magnetic body hub yoke, pushing the claw piece of a locking piece provided at a hub yoke into the notch of the resin-made hub member and unifying both. CONSTITUTION:At the center part of a circular yoke part 21, an angle shaft 22 fitted into a shaft hole 12 of a resin-made hub member 10 is protruded and at the circumference, a locking piece 23 is formed at the interval of 120 deg.. The locking piece 23 is sandwiched to two shallow slits 23A provided along a diameter direction and the tip part of the locking piece 23 is bent in the same direction as the protruding direction of the angle shaft 22 along the plane orthogonal to the diameter direction and comes to be a claw piece 23B. For the resin-made hub member 10 and a hub yoke 20, the circumferential surface of a notch 14 is firmly grasped by the claw piece 23B of the locking claw 23, further, the claw piece 23B is fitted into a flat part 14A of a notch 14 and unifying is executed without separating them in the circumferential direction and the shaft direction of both. Thus, the moving and separating of both can be prevented. |
