Abstract:
1. A starter comprising: a motor section; a housing which has a first side integrally formed continuous from the motor and a second side continuous from the first side and formed with a fixing section to be fixed to an engine, an output shaft which is housed in the housing, and which rotates by receiving a rotational force of the motor section; a gear mechanism which is housed in the housing, and which transmits a rotational force of the output shaft to a ring gear of an engine; a contact mechanism which is housed in the first side of the housing, and which performs electrical connection and disconnection to the motor section by contacting and separating a movable contact and a fixed contact according to ON and OFF of an ignition switch; and a gear movement mechanism which moves the gear mechanism according to the operation of the electrical connection and disconnection of the contact mechanism and coordinates the gear mechanism and the ring gear, wherein a fragile section is formed at a portion, between the contact mechanism and the fixing section on the housing, which avoids the contact mechanism so as to prevent a stress from being applied to the contact mechanism when the starter is shaken about the fixing section fixed to the engine as a reference point, and the fragile section is a housing groove section for weakening the stiffness of the housing.
