Patent ID: 6857331

Claim:
A starter (device) for a remote controlled miniature model car comprising: a transmission mechanism including a gear set, a rear cover provided at an output side terminal, a sleeve with an inner slip busting being attached to said rear cover; and a starter shaft having a first end inserted into said slip bushing, and a second end formed into a flared coupling plate so as to engage with a coupler of a rear engine shaft; wherein the slip bushing includes a longitudinal groove, when said starter shaft is inserted into said slip bushing, a pin is inserted through said starter shaft and said groove so as to fasten said starter shaft and said slip bushing together, said coupling plate formed at the second end of said starter shaft for engaging with said coupler of the rear engine shaft has a slanted surface such that said starter shaft is able to slidably reciprocate on said groove at an interval limited by said pin, after the engine builds up its normal speed, said coupler and said starter shaft are disengaged and the latter retrieves smoothly with the aid of said slanted surface such that the extra loss of frictional and mechanical power is saved.
