PROBLEM TO BE SOLVED: To develop a method for preventing such a problem that a partly broken gear, used for opening and closing in good order a cover using a plate folded and housed in the ceiling of an automobile, sometimes does not move when rotated, because the gear teeth hit on each other. SOLUTION: The first tooth of the partly broken gear wheel is reduced in size, and the tooth is formed in a saw-tooth shape. A sliding bearing is used with a spring together, and the gear wheel is shifted when the gear teeth hit on each other. |
