PURPOSE:To increase the angular range in which a handle is idly turned and is returned to its initial position, in a stick type parking brake in which the idle turning of the handle is enabled so that a brake is not inadvertently released. CONSTITUTION:A returning mechanism 30 for returning a handle 20 to its initial position is made up by a cam plate 31 that is slidable in the direction perpendicular to the axis of a stem 10 inside the handle 20, an energizing means 32 for energizing the cam plate 31 against the one end of the stem 10, and a circumferential cam 33 which is provided to the one end of the stem 10 and is slidably brought into contact with the end surface of the cam plate 31, and by which when the handle 20 is twisted and idly turned from the inital position, the cam plate 31 is slided in the direction resisting to the engergizing means 32. Further, the contacting position of the circumferential cam 33 and the end surface of the cam plate 31 in the state that the handle 20 is placed at the initial position is offset in the energizing direction of the energizing means 32 with regard to the center line of the stem 10. |
