<P>PROBLEM TO BE SOLVED: To enable the manually opening/closing operation of a vehicle door during the failure of a driving system in an automatic opening/closing device of the vehicular door. <P>SOLUTION: In the automatic opening/closing device of the vehicle door, a crank connected to a door opening/closing rod of the vehicle door is provided on one end 8a of a driven shaft 8, a driven gear 10 is provided on the other end 8b, and a driving gear 7 is engaged with the driven gear 10. The driven shaft 8 is inserted in a shaft hole 11a penetrated on the other end 8b side through a substrate 6 surface to back, a large diameter part 12 having the diameter larger than the shaft hole 11a is swollen on one end 8a side. An attachable/detachable spacer 15 is interposed in a space S between one end face 12a of the large diameter part 12 and a substrate surface 6a opposite thereto. When the spacer 15 is interposed in the space, an axial end face 10a of the driven gear 10 is slidably brought into contact with an opening end face 11b of the shaft hole 11a on a substrate rear surface 6b, the engagement state of the driven gear 10 with the driving gear 7 is maintained. A gear disengaging means which detach the spacer from the space S and disengages the driven gear 10 from the driving gear 7 by pressing the driven shaft 8 against the substrate rear surface 6b is provided on the spacer 15. <P>COPYRIGHT: (C)2009,JPO&INPIT |
