Abstract

[Problem] A drive unit (10) for driving, via a first and second geared cable (8, 9), a first and second member to be driven (sun roof and shade) provided to an opening part formed on the secured roof of a vehicle, wherein while being able to switch between a state in which the power from a motor (18) is transferred to both the first and second members to be driven and a state in which the power is selectively transferred to the first or second member to be driven, the member to be driven, in which the transfer of the power from the motor (18) is blocked, is prevented from moving during an impact when the vehicle collides in the selective transfer state. [Solution] The output path of the motor (18) is divided into a first and second output shaft (22, 42). Moreover, a first and second electromagnetic clutch (24, 44) for switching between connecting/disconnecting a first and second pinion gear (23, 43) to/from the first and second output shafts (22, 42) is provided, and each pinion gear (23, 43) is secured to a frame (3) so as to not be able to rotate when disconnecting from the clutches (24, 44).

A drive device for driving first and second driven members provided at an opening formed in a fixed roof of a vehicle, comprising:

a single motor;
a single drive gear directly connected to an output shaft of the motor or connected to the output shaft of the motor through a reduction gear;
first and second power transmission gears engaged with the drive gear;
a first output shaft connected to the first power transmission gear so as to rotate together with the first power transmission gear;
a second output shaft connected to the second power transmission gear so as to rotate together with the second power transmission gear;
a first pinion gear engaged with a first drive cable for driving the first driven member and supported so as to be fitted onto the first output shaft;
a second pinion gear engaged with a second drive cable for driving the second driven member and supported so as to be fitted onto the second output shaft;
a first electromagnetic clutch configured to switch between a connection state in which the first pinion gear is connected to the first output shaft so as to rotate together with the first output shaft and a disconnection state in which the first pinion gear and the first output shaft are disconnected from each other;
and
a second electromagnetic clutch configured to switch between a connection state in which the second pinion gear is connected to the second output shaft so as to rotate together with the second output shaft and a disconnection state in which the second pinion gear and the second output shaft are disconnected from each other,
wherein the first electromagnetic clutch includes first fixing means configured to unrotatably fix the first pinion gear to a fixed member of the vehicle in the disconnection state of the first electromagnetic clutch, and
the second electromagnetic clutch includes second fixing means configured to unrotatably fix the second pinion gear to the fixed member of the vehicle in the disconnection state of the second electromagnetic clutch.
