Patent attributes
An opening-closing device includes 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, and a clutch positioned between the driving source and the opening-closing mechanism and sifting an energization state can transmit a driving force of the driving source to the opening-closing mechanism and a non-energization state can not transmit the drive force. The clutch includes a drive portion and a driven portion. The drive portion and the driven portion contact each other by a first load which can transmit the driving force from the driving source to the opening-closing mechanism when the clutch is the energization state. The drive portion and the driven portion contact each other by a second load which can not transmits the driving force from the driving source to opening-closing mechanism when the clutch is the non-energization state.
