  • Starter
    Patent number: 6268670
    Abstract: To prevent damage or breakage of a pinion return coil spring employed in a starter, it is held between a first stopper and a second stopper which are coaxially arranged relative to an output shaft. Each stopper is provided with a cylindrical portion for restricting an inner diameter of the pinion return coil spring and controlling the movement of the pinion.

  • Vehicle starter with separate terminals for the motor and the excitation coil
    Patent number: 6201311
    Abstract: A starter in which a terminal is each provided for a motor side fixed contact point and an excitation coil separately, and the terminal of the motor side fixed contact point and the terminal of the excitation coil are of a snap-on type. Therefore, the work efficiency of connecting the motor side fixed contact point and the excitation coil of the electromagnetic switch can be improved.

  • Starter
    Patent number: 6157105
    Abstract: A contact shaft moving device that reduces the wearing of a pinion in a ring gear. More specifically, the contact shaft moving device moves a contact shaft in such a direction as to cause a moving contact to be in direct contact with a stationary contact after a plunger is attracted and moved for a certain period of time by an exiting coil. The movement of the plunger also assists in moving the pinion into abutment with the ring gear prior to contact between the moveable and stationary contacts.
