摘要： In a starter (1) for an internal combustion engine including a planetary gear type reduction gear unit (2) and a housing (17) for accommodating at least the reduction gear unit (2), a recess (51) is formed at a lower part (17a) of the housing (17) in an installed state of the starter (1) in a manner that the recess (51) is formed in an inner periphery of the housing (17) so as to define a drain passage (51) extending substantially axially, and a part (52) of an outer periphery of a first annular member (12), which constitutes a part of the reduction gear unit (2), protrudes into the recess (51). Thus, the protruding part (52) of the outer periphery of the first annular member (12) forms a labyrinth structure in the drain passage (51) defined by the recess (51) formed in the inner periphery of the housing (17), to thereby effectively prevent water from entering the housing (17) through the drain passage (51) without substantially impeding the passage of water from the housing (17) to the outside. This protruding part (52) is integrally formed in the first annular member (12), and therefore no additional component parts are required to make the labyrinth structure.

摘要： In an engine starter including a solenoid device for actuating a switch for the electric motor and to drive the pinion into mesh with the ring gear of an internal combustion engine, the solenoid device includes an armature outer member which moves in the direction to push out the pinion against the spring force of a first return spring in the energized state of the solenoid device, and an armature inner member which is resiliently urged by a second return spring, and is telescopically disposed with respect to the armature outer member with a coil spring interposed coaxially between them. An annular spring retainer is press fitted into the inner bore of the armature outer member to receive a corresponding coil end of the coil spring. The spring retainer is stamp formed from non-magnetic material so as to have cylindrical portion which is fitted into the bore of the armature inner member, a flange portion which is bent perpendicularly from the cylindrical portion in the manner of an inwardly directed flange in its installed state, and a guide piece portion which is bent perpendicularly with respect to the axial direction from the free end of the flange portion. The forming of the armature outer member is thereby simplified, and the guide piece portion supports the coil spring with a centering action. More importantly, the spring retainer which may be made of non-magnetic material can prevent any significant leakage of magnetic flux from the spring retainer.

摘要： In an engine starter comprising: a DC electric motor; an output shaft; a pinion unit; a reduction gear unit for transmitting an output of the electric motor to the pinion unit through the output shaft; a solenoid device for axially moving the pinion unit into mesh with a ring gear of the engine; a cover member for surrounding at least the pinion and the reduction gear unit, the cover member having an opening facing the electric motor; a substantially cylindrical member for surrounding the electric motor so as to serve as a yoke for the electric motor; a disk-shaped plate for covering an end of the electric motor facing away from the pinion unit; and an annular separator disposed between the reduction gear unit and the electric motor so as to separate them from each other, the disk-shaped plate is provided with at least one axial protrusions for engaging an inner surface of one end portion of the substantially cylindrical member so as to align the disk-shaped plate and the substantially cylindrical member with each other, and an annular separator is provided with at least one axial protrusions for engaging an inner surface of the other end portion of the substantially cylindrical member so as to align the annular separator and the substantially cylindrical member with each other, and the annular separator is fitted into the opening of the cover member. Thus, since the disk-shaped plate, the substantially cylindrical member (yoke), the annular separator and the cover member are all aligned with each other without using the outer surface of the yoke, the outer surface of the yoke is allowed to be formed with lower precision. This eliminates the need of an additional step of machining or otherwise finishing the outer surface of the yoke with high precision, to thereby simplify the manufacturing process and lower the manufacturing cost of the yoke.

摘要： In an engine starter according to the present invention, an annular stopper disposed between the pinion unit and the solenoid device so as to determine the rest position of the pinion unit is formed with a tongue projecting radially outwardly from its outer periphery, and a shoulder surface defined in the gear cover so as to abut an end surface of the solenoid device and thereby determine the axial position of the solenoid device is formed with a recess for receiving the tongue of the annular stopper, with the tongue and the recess being dimensioned with respect to each other so as to allow the tongue to be resiliently interposed between the recessed part of the shoulder surface and the end surface of the solenoid device and to define a space which accommodates a corresponding deformation of the tongue. Thus, since a space which accommodates the deformation of the tongue of the stopper is provided within the recess of the shoulder surface, the tongue can be resiliently deformed so as to support the annular stopper steadily without affecting the axial position of the solenoid device.

摘要： In an engine starter comprising a pinion slidably fitted on the output shaft for driving a ring gear of an engine that is to be started, and a one-way clutch having a first end secured to the pinion and a second end which is engaged by the output shaft via spline means, a compression coil spring is interposed between a stopper secured to the output shaft and an annular shoulder defined in a cylindrical extension of the second end of the one-way clutch. Therefore, even when the pinion is forced into a high speed rotation by the engine which has been started by the engine starter, the pinion simply rotates freely, and no friction is applied to the compression coil spring or the stopper. Also, by receiving the compression coil spring in an annular space defined between the cylindrical extension of the second end of the one-way clutch and the output shaft, the compression coil spring can be protected from the centrifugal force which acts upon the compression coil spring when the output shaft of the engine starter rotates at an extremely high speed.
