摘要： A power steering system to reduce the moment of inertia of the torque limiter and to accurately determine pressing force by a forcing member is provided. The torque limiter of the system has a basic structure in which a substantially-cylindrical rotating member (23) which is rotatable together with one of the output shaft (20, 120) and the input shaft (21); and a rotated member (24, 124, 324, 424) which is rotatable together with the other of the output shaft and the input shaft, and which is forced toward the rotating member side by a forcing member (26) supported by the rotating member. Typically, the rotating member is a substantially-cylindrical limiter cover with a bottom, and the rotated member is a limiter plate contained in the limiter cover. The forcing member may be supported by a concave portion formed in an inner-peripheral area of the limiter cover, or may be supported by a projecting portion which is formed by deforming the cylindrical portion of the limiter cover toward the inside. In the above basic structure, the rotated member may separately comprise a cylindrical portion (124A, 324A, 424A), on the inner-peripheral surface of which plural splines are formed in parallel with its axial direction, these splines being engaged with the splines formed in the outer-peripheral surface of the other of the output shaft and the input shaft; and a flange portion (124B), which is forced toward the rotating member side, by which the flange portion functions as a friction clutch. In this structure, efficiency of forming the limiter plate can be improved.

摘要： In molding coils wound around a motor rotor with resin material in a die assembly, the coil ends projecting from either axial end of the motor core are compressed radially inward by small diameter portions formed in the die surface. Because the unnecessary deposition of the resin material over the coil ends is minimized, the material cost can be reduced. Also, the elimination or the reduction of the need to eliminate excess resin material from the coil ends simplifies the production process, and reduces the production cost. Additionally, the reduction in the mass of the resin material over the coil ends, as well as the constraining of the coil wire into a relatively radially inner parts reduces the moment of inertia of the motor rotor, and can thereby improve the performance of the motor.

摘要： In a brush holder device, in which an action-side end portion (22a) of a torsion spring (22) is engaged with a torsion spring engaging groove (25) recessedly provided in an end surface of the brush (24) on the side opposite to a commutator (23), so that the elastic force of the torsion spring presses the brush against the commutator (23), a first inclined surface (26) is formed in the end surface of the brush (24) so as to incline at an angle of 15° relative to a plane perpendicular to the axis of the brush, and second inclined surface (27) is formed in the engaging groove (25), being superposed on the first inclined surface (26). Further, a pigtail (28) is connected to the brush at an offset point relative to the engaging groove (25). Because of the second inclined surface, the torsion spring can suppress so-called "wild behavior" of the brush, and thereby, can prevent brush sound. The angle of inclination of the first inclined surface can be set at a small value, the brush can be molded using a molding die.

摘要： In bottoms of three bolt head receiving holes (26) of a stay body (11) made of resin, there are embedded respective collars (30) by insert molding, in such a manner that both end surfaces of each collar are exposed. In an outer peripheral surface of the collar body (31), a knurled portion (32) is formed to leave a non-knurled portion (33) in a lower end portion of the collar body (31). The collar (30) is embedded in the stay body by insert molding in such a state that a slightly chamfered seating surface (34) of the non-knurled portion (33) is slightly projected from a lower end surface of the stay body (11). Since a resin adhered portion is not formed on the seating surface of the non-knurled portion of the collar, the seating surface of the collar and a fastening surface (27) of a bracket (8) is fastened by bolts (29) to be in tight contact with each other, and the stay (10) and the bracket (8) can be maintained in desired parallelism.
