に記載の内燃機関始動装置。[Claims for Utility Model Registration] (1) A plurality of cam protrusions 20a protruding from the outer peripheral surface
, one side of each cam protrusion serves as a clutch pawl contact surface 20c, and the clutch cam 20 is rotationally driven by the starting electric motor 15 with each clutch pawl contact surface facing forward in the rotational direction. , a clutch pulley 25 having a peripheral wall portion 25a surrounding the clutch cam and fixed to the output shaft 10 of the internal combustion engine; and a clutch pulley 25 provided corresponding to each of the plurality of cam protrusions 20a on the rear end side of the clutch pulley 25; It is rotatably supported inside the peripheral wall of the cam via a shaft 29, and there is a connecting position where the tip surface 27b abuts the clutch pawl contact surface 20c of each cam projection 20a, and a connection position where the tip surface separates from the clutch pawl contact surface. In the internal combustion engine starting device, the clutch pawl 27 is provided with a clutch pawl 27 that rotates between a detached position and a disengaged position, and a spring that biases the clutch pawl 27 toward the coupled position. The clutch cam 2 is formed in the shape of a cylindrical surface substantially coinciding with the rotation center of the clutch pawl, and the clutch pawl abutting surface 20c is in contact with the distal end surface 27b of the clutch pawl.
A cylindrical clutch pawl receiving surface 25b1 is formed on the inner periphery of the clutch pulley 25 to receive the rear end surface 27a of each clutch pawl when driving force is applied from the zero side to the output shaft of the internal combustion engine through the clutch pulley 25. , when the clutch pawl contact surface 20c is in contact with the distal end surface 27 of the clutch pawl, the direction of the force acting from the clutch pawl contact surface side to the clutch pawl side is from the center of the distal end surface of the clutch pawl to the An internal combustion engine starting device characterized in that the positional relationship between the clutch pawl and a clutch pawl contact surface is set so as to substantially follow a straight line O-O passing through the center of rotation of the clutch pawl. (2) Claim 1 characterized in that the clutch pulley 25 is integrally provided on a bottom wall portion of the flywheel 11 attached to the output shaft of the internal combustion engine.
The internal combustion engine starting device described in .
