ABSTRACT:
A gear disengaging mechanism for use in a movable toy which mechanism disengages automatically the engagement between a first gear receiving the rotation from a driving section and a second gear being pushed by a spring. The bearing hole for the shaft of the second gear is a slot in which one end portion of the shaft is moved. The shaft that is moved in the bearing hole is urged toward one side by the spring member one end of which is fixed to a frame body, thus gears are releasably engaged together. When a gear on the driven side is forcibly stopped, the gear shaft is shifted along the bearing hole against the force of the spring member and the engagement of gears is released. Further, between the driving section and the driven section is disposed a gear changing mechanism with which the gear change is carried out by moving a gear shaft in its axial direction.
