Abstract: To secure sufficient attractive force against a plunger, an overrunning clutch is arranged so that one end of a thrust spline is positioned so as to maintain a prescribed interval from the end of the plunger in the condition where the plunger is unexcited by an exciting coil and the outside periphery of the output shaft corresponding to the prescribed interval is covered by a cylinder body formed of a non-magnetic material or less permeable material.

Abstract: To reduce abrasion of the pinion and the ring gear, a coil spring and a plate are arranged between the inner circumference of the plunger and the output shaft. The plate is adapted to the rear end of the thrust spline of the over-running clutch to transmit the elastic force of the coil spring to the thrust spline.

Abstract: The present invention provides a brush holder assembly structurally avoiding electrical short circuiting incidents involving positive-side leads, improving productivity and enabling costs to be reduced. Tabs for securing positive-side brush holder frames are disposed in diagonally opposite positions. The tabs disposed on the side out of which the leads pass are positioned radially outside the range of movement of the positive-side leads and the tips of the tabs are bent in directions in which the positive-side leads do not come into contact therewith. On the other hand, the tips of the tabs disposed on the opposite side from the side out of which the leads pass are bent in the opposite direction to the tips disposed on the side out of which the leads pass.

Abstract: To fully secure the precision around an output shaft, an electromagnet is axially held in position between a center bracket and a front bracket which form an enclosing member for a starter.

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.

Abstract: The present invention provides a brush holder assembly enabling a common brush holder frame to be used regardless of the direction in which a lead is to pass out, improving productivity and preventing decreases in quality due to the incorrect mounting of parts, etc. A plurality of brush holder frames are secured to a base such that the openings of respective brush receiving recesses face a passage and the axes of the brush receiving recesses are directed towards the central axis of the passage. Lead outlet grooves are disposed in both sides of each of the brush holder frames so that each extends from a first end towards a second end and joins the respective brush receiving recess to the outside. Brushes are inserted into the brush receiving recesses so that leads attached to the side thereof pass through one of the lead outlet grooves in said brush holder frames and are held by each of the brush holder frames.

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.
