Patent ID: 7140150

Claim:
An opening-closing device comprising: a driving source; an opening-closing mechanism for opening and closing an opening-closing member provided at a vehicle body by operation of the driving source; a clutch positioned between the driving source and the opening-closing mechanism; the clutch being shiftable between an energization state in which the clutch transmits a driving force of the driving source to the opening-closing mechanism and a non-energization state in which the clutch is unable to transmit the driving force of the driving source to the opening-closing mechanism; the clutch includes a drive portion and a driven portion; wherein the drive portion and the driven portion contact each other by a first load which is able to transmit the driving force from the driving source to the opening-closing mechanism when the clutch is in the energization state; and wherein the drive portion and the driven portion contact each other by a second load which permits operation of the opening-closing mechanism to open and close the opening-closing member without the driving force of the driving source when the clutch is in the non-energization state, and the drive portion is pushed to contact the driven portion by an elastic member when the clutch is in the non-energization state.
