[0010]

According to this deflector actuating device, for example, when the opening / closing member is fully closed, the sliding member is restricted to the restrained position deviated from the slidable position by the engaging member abutting on the outer surface of the driving member. It is in a lying storage position. In this state, when the driving body is moved back, the opening / closing body slides and opens. When the driving body interlocking with the opening / closing body moves out of the side contact state area of the engagement body during this operation, the sliding member whose restriction has been released slides from the restrained operation position to the operation position by the biasing spring. At the same time, the deflector switches from the retracted position to the upright operating position. Thereafter, the driving body moves back without exerting an excessive load, and the sliding opening state of the roof opening can be obtained.

Next, in order to set the deflector in the retracted state, when the driving body is moved forward, the engaging body is pressed by the driving body by the forward movement. This pressing causes the sliding member to slide from the operating position to the restraining position, and upon completion of the restraining position deviating from the slidable position, the deflector assumes the collapsed storage posture. At the same time, after the driving body is in the disengaged state in which the engagement with the engaging body is released, the driving body continues to move forward without applying an excessive load. Thus, the fully closed state of the opening / closing body is obtained, and the sliding member is positioned at the restraining position by the side contact state where the outer surface of the driving body and the engaging body abut.
