ABSTRACT:
The present invention relates to an apparatus for automatically attaching and detaching such exterior parts as doors, a trunk, and a hood, etc. which are openably mounted to a vehicle body by way of tightening devices such as pins, bolts, etc. on the assembling line of a vehicle. The invention relates to a trunk or hood attaching and detaching apparatus in which a trunk or hood is opened with respect to a vehicle body by a trunk or hood opening and closing mechanism. A holding member which constitutes the holding mechanism is closed by a driving device positioned on a base plate, so that the holding member moves and follows the position of the trunk or hood, thereby causing the trunk or hood to be held. Also, the position of the screw member screwed in the vehicle body is detected by a detection mechanism, and simultaneously the position of a nut runner mechanism is compensated on the basis of the position of the screw member detected by the detection mechanism. Thereafter, the screw member can be tightened and loosened by the nut runner mechanism.
