Due to be pinion 8 with clutch inThe structure that body 7a separates, therefore after the end face of pinion 8 and the end face of gear ring 12 collide each other, by electromagnetic switch 10Attraction, make via lever to restrict towards the pinion 8 of the motion of axial gear ring side except colliding to the end face of gear ring 12Outside pinion moving body 6 make elastomer 9 bendings while till moving to stop-motion body 7b. Then, pinion 8After colliding each other with the end face of gear ring 12, rotate caused gear ring by the rotation of pinion 8 or because of the inertia of engineEither party in 12 rotation, utilizes the collision each other of mutual end face that pinion 8 is nipped to gear ring 12, is becomingWhen this state, pinion 8 is further attempted nipping to gear ring 12 towards axial gear ring side shifting.
Now, the pinion 16 of pinion 8 or in the past structure is in order to nip to gear ring 12 and towards axial gear ring side shifting,And this amount of movement is to nip successfully or failed key factor.
, make by the rotation from the end face collision status of pinion 8 and pinion 16 and gear ring 12 end face thatThereby in the time that this disengaging can be nipped, be greater than the axial of gear ring chamfered section in the distance L 5 that moves axially of pinion 8In the situation of the axial length L 3 of length L 2 and/or pinion chamfered section 14, pinion 8 will successfully be nipped to gear ring12, but move axially at pinion 8 that distance L 5 is less than the axial length L 2 of gear ring chamfered section and/or pinion fallsIn the situation of the axial length L 3 in bight 14, gear ring chamfered section 13 can bump each other with pinion chamfered section 14, littleGear 8 cannot be nipped swimmingly to gear ring 12, causes nipping unsuccessfully.
Known by above content, with respect to the axial internal clearance L4 of the pinion 16 of structure in the past, due to by pinion 8Be made as isolating construction and start to nip from making the state elastomer 9 bendings, therefore axially moving of pinion 8 of the present inventionMomentum L5 is the pinion amount of movement L5 (=L4+L1) adding after pinion stroke L1, so with respect to structure in the pastPinion 16, structure of the present invention can significantly improve the nipping property of gear ring 12 of pinion 8 in rotating towards inertia, thereby canA kind of engine starting device of restarting requirement of response engine is delicately provided.
In addition,, by the bounce of bending elastomer 9, the pinion 8 that makes to be lighter than pinion moving body 6 far away can courtAxially gear ring 12 side shiftings, therefore pinion 8 of the present invention can be with the pinion moving body 6a's considerably beyond structure in the pastThe speed of translational speed moves.
In addition, for example, in the technology of patent documentation 1, must utilize each o to carry out pinion release and contactOpen and close, therefore with respect to engine starting device in the past with comparatively complicated for the structure of electromagnetic switch, little thereby existence is difficult toThe situation of type lightweight or low price. And then, when utilizing ECU etc. to control engine starting device, with respect in the pastCircuit and the relay of 1 system of the electromagnetic switch of engine starting device, essential 2 systems of technology of patent documentation 1Circuit and relay, to utilize each o to carry out pinion ejector unit and contact opening/closing unit, lead thereby existCause the situation of the cost rising of vehicle side.
