ABSTRACT:
The device is provided with a positioning mechanism having a positioning member, a switching mechanism for switching the positioning mechanism from an operating mode thereof to a non-operating mode and a friction mechanism for applying a resistance to rotation of the lever body when the positioning mechanism is switched to the non-operating mode. Gaps are provided between the positioning member and the lever body, whereby the positioning member is adapted to follow the rotation of the lever body with a predetermined delay when the positioning member is in the operating mode. When the positioning mechanism is switched to the non-operating mode, the positioning member follows the rotation of the lever body without delay because the rotational idling of the positioning member caused by the gaps is eliminated.
