Abstract:
1. A starter for starting an internal combustion engine of a vehicle, comprising: an electric motor provided with an armature, a brush, and a casing that encloses at least the armature and the brush, current being supplied to the armature via a motor circuit; an electromagnetic switch provided with first and second fixed contacts, a movable contact, an electromagnet that moves back and forth to the movable contact in a predetermined direction so as to electrically connect and disconnect the first and second fixed contacts, and a cover that covers at least the first and second contacts and the movable contact, the predetermined direction being parallel to a longitudinal direction of the armature of the motor, the electromagnet being provided with only a single coil generating a drive force for moving the movable contact; an electrically conductive connection member that is arranged to link the motor and the electromagnetic switch through the casing of the motor and the cover of the electromagnetic switch and electrically connects the brush of the motor and the second fixed contact in the electromagnetic switch, the connection member including an end part arranged in the cover of the electromagnetic switch, the end part of the connection member functionally providing the second fixed contact, the single coil has one end portion connected to a terminal which is fixed to the cover of the electromagnetic switch, and an other end portion connected to a grounding side, such that the single coil is electrically separated from the motor circuit; and a holding member that is made of insulating and elastic material and that fixedly holds, between the motor and the electromagnetic switch, the connection member inserted through the holding member and that is inserted through the casing of the motor and the cover of the electromagnetic switch, wherein: the connection member penetrates the casing at a part of the casing that is substantially perpendicular to an elongating direction of the connection member; and the connection member penetrates the cover at a part of the cover that is substantially perpendicular to the elongating direction of the connection member.
