Disengagement of two train wheels

摘要

PROBLEM TO BE SOLVED: To provide a clock mechanism 100 for disengaging a train wheel. A clock mechanism (100) includes a gear set (110), an disengagement member (120), a holding member (121), and a control member (130). The gear set (110) is driven by the first car (111), the second car (112), and the first car (111) or drives the first car (111). And / or an intermediate vehicle (113) configured to drive the second vehicle (112). In the holding member (121), the disengagement member (120) controlled by the control member (130) moves the intermediate wheel (113) between the engagement position (101) and the disengagement position (102). Occasionally, it holds the first car (111) and / or the second car (112). Therefore, the clock mechanism (100) is held in place while the clock mechanism is disengaged. [Selection diagram] Fig. 2
