<p>Some of the components of a parking brake mechanism are incorporated between an inner side case (45) and an outer side case (46), the two case (45) and (46) are combined by engaging lock holes (51, 51) and lock claws (55, 55), and an inner side auxiliary assembly (59) is formed. In this state, the diameter of circumscribed circle of the lock claws (55, 55) is configured to be smaller. Then, when the inner side auxiliary assembly (59) is incorporated in the cylindrical space (9a), the two lock claws (55, 55) are engaged with a lock concave (61) which is formed on the inner peripheral surface of the cylindrical space (9a) by making the two lock claws (55, 55) protrude greatly from the outer peripheral surface of the inner side case (45).</p> |
