Abstract: An internal combustion engine starter having a high starting performance has a first cranking mechanism including a self-starting motor 13 and a second cranking mechanism including a kick lever 18. The second cranking mechanism causes a crankshaft 1 to rotate mechanically during the beginning of its rotation which requires a high torque, and the first cranking mechanism places it in continuous rotation.

Abstract: An improved engine starter has a DC motor with a rotor shaft drivingly connected to an output shaft by a planetary reduction gear, the sun gear of the reduction gear being formed on the outer surface of the rotor shaft and the ring gear of the reduction gear being located on the inner surface of the yoke of the DC motor. The improvement comprises the yoke having a support portion integrally formed thereon which rotatably supports a one-piece end of the output shaft which is connected to the rotor shaft. Preferably, the yoke is formed by deep drawing of mild steel. A dust preventing member forms a labyrinth seal around the rotor shaft and prevents dust from entering the motor from the reduction gear.

Abstract: An automatic starter for a vehicle equipped with an automatic transmission with which excessively abrupt starting of the engine of the vehicle is inhibited. The automatic starter includes an accelerator pedal having first and second accelerator pedal members. The first accelerator pedal member is attached to the second accelerator pedal member through a returning elastic member so as to be biased apart. A rod extends downwardly from the second accelerator pedal member through the first accelerator pedal member with the lower end of the rod forming the operating element of a solenoid. The two accelerator pedal members carry contacts which are closed when the second accelerator pedal member is depressed downwardly against the first accelerator pedal member. Upon the starting of the vehicle, the solenoid is energized to hold the two accelerator pedal members together.
