PURPOSE:To realize the prompt and easy installation of a driving mechanism by a structure wherein a clutch, which disconnects the connection between a cover adjusting unit and the switching device of a motor actuated in response to the position of the cover adjusting unit, is provided between said cover adjusting unit and said switching device. CONSTITUTION:A sliding cover 10 is driven through a cover adjusting unit 8 and 9 so as to be opened and closed by a cable 7 operated with the pivoting of the pinion 35 of a transmission 25 caused by the rotation of a motor shaft 31. On the other hand, a clutch consists of the cable 7 and a moving pinion 40, which is installed to a pinion shaft 39 housed in a clutch housing 37 and the connection and disconnection of the clutch are performed by axially shifting the shaft 39. In addition, a ratchet wheel 42, which forms a stepwise drive gearing together with a trip 22. The trip 22 is provided with a cam 22a, by means of which the switch 13 in the controlling circuit of motor 6 is opened and closed in order to perform synchronous control of the cover 10 and the switch 13. |
