摘要

A drive device for opening and closing a vehicle top includes a pair of control devices each fixed in the side of the vehicle body, a falling pillar swingably supporting the vehicle top on the vehicle body and a pair of extendable link mechanisms that include link rods which are inclinable and which couple a swinging arm of the respective control device with the falling pillar. Each of the control devices includes a housing in which is rotatably positioned at least a portion of an output shaft for rotating the swinging arm, a driving device attached to the housing and generating a rotary driving force, a first reduction gear stage formed as a worm drive which is coupled with the driving device and which is housed in the housing, and a second reduction gear stage formed as a spur gear drive which is coupled with the worm drive for driving the output shaft and which is housed in the housing. A clutch disk is positioned on a gear shaft of a transmission gear in an axially movable manner and the clutch disk is substantially rotationally fixedly positioned on the gear shaft. The transmission gear forms a part of the spur gear drive. The clutch disk includes a connecting arrangement located in a side thereof for generating a claw clutch engagement with a connecting arrangement formed in a side of the transmission gear. A transferring device transfers movement of the transferring device to the clutch disk along the gear shaft in order to engage and disengage the claw clutch engagement.
