As can be seen, the open roof 7 is driven at a normal speed during the opening operation until the rotation angle θ changes from α to β, but the rotation angle θ changes from β to γ (open position). During that period, the driving speed is reduced. During the closing operation, the drive is driven at a normal speed until the rotation angle θ changes from β to α, but the drive speed is reduced until the rotation angle θ reaches from α to 0 (closed position).

Further, the driving speed is reduced in the same manner as the final stage of the opening / closing operation during the period when the rotation angle θ changes from 0 to α in the initial stage of the opening operation and during the period when the rotation angle θ changes from γ to β in the initial stage of the closing operation. It

If so,
By detecting this by the upper position detection switch 17 and decelerating the roof motors Mr and Mr of the roof drive device 21, the driving speed at the end of the opening operation and the end of the closing operation of the open roof 7 can be reduced. Therefore, the impact force generated between the open roof 7 and the floor stopper 19 and the front header 6 at the end of the opening operation and the closing operation of the open roof 7 can be reduced.

As a result, it is possible to prevent damage to the abutting portions of the open roof 7, the floor stopper 19, and the front header 6, and to prevent the occupant from feeling uncomfortable due to the impact generated at the end of the opening / closing operation of the open roof 7. Of.
