PURPOSE:To improve the extent of productivity by reducing the number of parts items with an output arm easily energized, while making it into a very simple one in structure and setting it down to an advantageous one from the standpoint of cost. CONSTITUTION:An output arm side return spring engaged part 7a, consisting in a hook form, is installed in an output arm 7 which releases a parking brake 30 by means of drive to the release side, while a projected-form casing side return spring engaged part 2a is installed in a casing 2, one end of a return spring 8 is engaged with the output arm side return spring engaged part 7a and the other end of this return spring 8 is engaged with the casing side return spring engaged part 2a, and simultaneously the spring 8 is assembled to the output arm 7 at the concentric position and then the output arm 7 is assembled in a state of energizing it to the counter release side of a brake release lever 34, that is a parking brake releasing actuator 1. |
