[0007]

[Operation and effect] Adjustments for window doors are
The bolt extending from the bracket at the lower end of the window guide is moved back and forth with respect to the inner panel, and the length of the bolt protruding from the inner panel is changed.

Since one bolt is provided on the bracket of the window guide, only one nut needs to be operated for adjustment, and quick adjustment is possible. Further, since the central axis of the bolt is on the central axis of the window guide, the twist applied to the window guide by the adjustment is small.

In one aspect, the bolt has a threaded portion that is screwed into the bracket of the window guide, and the threaded portion is screwed onto the bracket to provide a substantial support length for the lower end of the window guide. Becomes shorter. For example, when the door is strongly closed, a centrifugal force acts on the window, and a force based on the centrifugal force acts on the lower end of the window guide. The influence of this force increases as the support length increases, and the support rigidity of the window decreases. However, according to this aspect, the support rigidity is small because the support length is short.
