Claims

[Claims for Utility Model Registration] (1) A rotating shaft member 40 that is rotatable with respect to the housing 36, a reel 48 around which a rope 52 is wound, and the reel 48 connected to the rotating shaft member 4.
0 from the reel 48 to the rotating shaft member 4.
The first one allows transmission of rotational force in only one direction to zero.
A one-way clutch 50, a rotating plate-like member 58 driven by an electric motor 62, and a rotating plate-like member 5.
8 on the rotary shaft member 40 and allows transmission of rotational force in only one direction from the rotary plate-like member 58 to the rotary shaft member 40;
0, and automatic clutches 70, 7 that connect the rotating shaft member 40 and the output shaft 20 of the engine 10 and disconnect them when the rotational speed of the output shaft 20 increases.
8. An engine starting device comprising: (2) The automatic clutch 70 includes a locking member 46 that rotates integrally with the rotating shaft member 40, and a locking member 46 that rotates integrally with the output shaft 20 so as to be swingable and rotate integrally with the output shaft 20. and a biasing means 76 that urges the locked member 72 with a predetermined urging force so that the locked member 72 is locked with the locking member 46. The engine starting device according to claim 1, further comprising: (3) The automatic clutch 78 has a claw member 80 which is rotatably coupled to the rotary shaft member 40 at its base end and has a claw portion 82, and a claw member 80 which is fitted onto the stationary shaft portion 38 with a predetermined frictional force. 80 toward the center of the shaft portion 38; and a notch 92 that rotates integrally with the output shaft 20 and can be locked with the claw portion 82. Claim 1
Starting device for the engine described.
