Engine starter with improved fixing structure of auxiliary electromagnetic switch
First Claim
1. A starter for starting an engine, the starter comprising:
- a starter main body including a motor that includes a hollow cylindrical yoke and that generates torque upon being supplied with electric power;
a main electromagnetic switch configured to selectively open and close an electric circuit that supplies the electric power from a battery to the motor;
an auxiliary electromagnetic switch configured to selectively switch the electric circuit between a high-resistance path and a low-resistance path, the electric power being supplied from the battery to the motor through a resistor along the high-resistance path, and the electric power being supplied from the battery to the motor by bypassing the resistor along the low-resistance path; and
a fixture to which the auxiliary electromagnetic switch is fixed, the fixture being fixed to only one of the starter main body and the main electromagnetic switch, wherein;
the fixture is configured as a fixing band that includes a band portion and a seat portion, the band portion having the shape of an incomplete hollow cylinder with an opposite pair of circumferential ends, the seat portion having (i) a pair of side walls that protrude radially outward respectively from the circumferential ends of the band portion and (ii) an end wall that extends to connect radially outer ends of the side walls,the band portion of the fixing band surrounds a radially outer surface of the yoke of the motor and is fixed to the radially outer surface,the auxiliary electromagnetic switch is fixed to an outer surface of the end wall of the seat portion of the fixing band,the band portion has an inside diameter greater than the outside diameter of the yoke of the motor and at least one tapped hole formed through a circumferential wall of the band portion, andthe band portion is fixed to the radially outer surface of the yoke of the motor by a bolt tightened into the at least one tapped hole of the band portion to press the bolt against the radially outer surface of the yoke.

Abstract
Disclosed is a starter for starting an engine. The starter includes a starter main body, a main electromagnetic switch, and an auxiliary electromagnetic switch. The starter main body includes a motor that generates torque upon being supplied with electric power. The main electromagnetic switch is provided for selectively opening and closing an electric circuit for supplying electric power from a battery to the motor. The auxiliary electromagnetic switch is provided for selectively switching the electric circuit between a high-resistance path and a low-resistance path. The starter is characterized in that the auxiliary electromagnetic switch is fixed to a fixture, and the fixture is fixed to only one of the starter main body and the main electromagnetic switch.
