It is possible to release the engagement pin of the lift arm by the engagement portion of the lift arm, and the engagement portion of the lift arm is disengaged from the engagement pin of the link, so that only the lift arm moves the engagement pin of the link. The guide rail becomes stationary with respect to the tip of the main arm, so that the rise of the window glass accompanying the swing of the main arm can be stopped, and the window can be stopped. Since prevent accidents due to the rise accompanying the swinging of the main arm of Dogarasu in advance, it is possible to increase the rise time of the safety of the window glass.

It should be noted that, even if the window glass is prevented from rising due to the swing of the main arm, the lift arm can swing in the direction in which the window glass is lifted. As a result, a large current does not flow to the motor due to the stoppage of the rise due to the swing of the main arm of the window glass, and it is possible to prevent the motor from burning.
