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.

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.

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.

To prevent an attracting force to the plunger from becoming insufficient, at least one of an output shaft and a thrust spline is formed from magnetic material having a lower relative permeability than iron.

To prevent powder caused by wear of brushes from entering a contact chamber, a first stationary contact is electrically connected to a battery and a second stationary contact is connected to positive brushes, wherein a contact bracket is provided to hold the first stationary contact, and a contact chamber cover is provided to interpose and hold the second stationary contact between the contact chamber cover and the contact bracket so that the contact chamber can be kept in an airtight state.
摘要:
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.

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.
摘要:
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.

A shift lever assembly includes a shift lever having a fulcrum portion provided with a pair of pin bores for supporting portions of both ends of a pin, a first arm portion extending from one side of the fulcrum portion in a direction perpendicular to the axis of the pair of pin bores, a second arm portion for engaging the overrunning clutch extending from the other side of the fulcrum portion in a direction perpendicular to the axis of the pair of pin bores, and a housing recess formed from a root portion of the second arm portion across to the first arm portion so as to be open on one side in a direction perpendicular to both the axis of the pair of pin bores and the direction of extension of the first and second arm portions; and a lever spring housed within the housing recess such that a first end thereof is placed in contact with a surface at the tip of the first arm portion and a second end thereof is placed in contact with the floor of the housing recess at the end nearest to the root portion of the second arm portion, the spring being bent towards the floor of the housing recess and elastically held against the shift lever by the pin inserted into the pair of pin bores, and the first end thereof engaging a hook on the plunger.

The commutator is disposed within the case of the starter motor at the end nearest to the pinion, an arc-shaped recess is formed in the outer circumferential wall of the case radially outside the commutator so as to indent between the brushes, and the electromagnetic switch is accommodated in the arc-shaped recess so as to be positioned radially outside the commutator and between the end surface of a core portion of the armature nearest to the commutator and the end surface of the over-running clutch nearest to the commutator, with the central axis thereof generally parallel to the rotor shaft, and with part thereof positioned radially inside the outer circumferential surface of the starter motor.
