Claims

[Claims for Utility Model Registration] (1) An electric motor having a hollow armature rotation shaft, a front machine frame provided on the front end side of the electric motor and housing a driving force transmission device therein, and an electric motor having a hollow armature rotation shaft; a planetary gear reduction device that decelerates the rotation of the shaft and transmits it to the driving force transmission device; and a planetary gear reduction device that is installed between the yoke of the electric motor and the front machine frame, and has an inner surface of the planetary gear reduction device on its inner peripheral surface. An internal gear forming body in which a toothed gear is formed extends from the rear end side of the motor into the yoke of the motor, and its end portion is screwed to the yoke side end surface of the internal gear forming body to connect these yokes. a first through bolt that fixes the internal gear forming body; and a first through bolt that screws into the front machine frame side end surface of the internal gear forming body to fix the front machine frame and the internal gear forming body. A coaxial starter with two through bolts. (2) an electric motor having a hollow armature rotation shaft; a front machine frame provided on the front end side of the electric motor and housing a driving force transmission device therein; A planetary gear reduction device that transmits the driving force to the driving force transmission device, and is installed between the yoke of the electric motor and the front machine frame, and has a diameter larger than the inner circumferential diameter on the front machine frame side along the inner circumferential surface thereof. A metal concave forming body having a concave portion, an internal gear formed integrally with resin in the concave portion of the concave forming body and having an internal gear of the planetary gear reduction device formed on an inner peripheral surface, and the electric motor. Extending within the yoke of the motor from the rear end side,
A first screw whose end portion is screwed onto the yoke-side end surface of the recess formation body to fix the yoke and the recess formation body.
A coaxial starter comprising: a through bolt; and a second through bolt that is screwed into an end surface of the recess forming body on the machine frame side to fix the front machine frame and the recess forming body.
