Claims

[Claims for Utility Model Registration] (1) An electric motor that has a tubular armature rotating shaft and generates rotational force for engine starting when energized, and a motor that receives thrust at the time of starting the engine and extends along the axis of rotation. The output rotating shaft is movably provided at the front end thereof and has a pinion that meshes with the starting ring gear on the engine side, and transmits the rotational force transmitted from the electric motor to the ring gear at the time of starting the engine. The pinion mechanism is energized when the starter switch is turned on, and the electromagnetic force generated by the energization urges the movable body forward to provide the above-mentioned thrust, and the contact portion connects to the intermediate portion between the fixed contact and the movable body. an electromagnetic switch that turns on a switch consisting of a movable contact provided to energize the electric motor; A starter for an engine that is inserted from opposite directions, wherein the rear bracket of the electric motor is molded with plastic, and a bearing that supports the rear end of the armature rotating shaft is fitted in the front part of the rear bracket. A recess is provided, and a recess in which the fixed contact is installed extends from the rear end to the front of the rear bracket, and has an opening at the front end to form the opening in the case of the electromagnetic switch that accommodates the rear of the movable body. A core having a hole that is fitted into the inner circumferential surface of the case and guides the intermediate portion of the movable body to the recess of the rear bracket is provided, and a rear end portion of the rear bracket is provided in a shape corresponding to the shape of the core. A starter for an engine, characterized in that a notch communicating with the recess of the rear bracket is provided in the rear bracket, and a rear end of the rear bracket is fitted into an inner circumferential surface of the case. (2) The commutator fitted to the rear part of the armature rotating shaft is a face-type commutator having a flat contact surface that contacts the brush tip of the brush and the retainer, and the bearing recess of the rear bracket and the rear bracket. 2. The engine starter according to claim 1, wherein a holder hole for movably housing the brush and retainer is provided in a portion of the rear bracket around the recess.
