Abstract: Provided are a motor device and a method for manufacturing the same that can accurately and consistently provide a support shaft to a case and enhance the strength for fixing the support shaft to the case. A small-diameter part having a smaller diameter than a large-diameter part is formed through drawing. The large-diameter part and a step part are embedded in a gear case. The small-diameter part is exposed outside the gear case. The dimensional accuracy (dimensional tolerance ±α) of the external diameter of the small-diameter part is enhanced. The small-diameter part can be set, without rattling, in a lower mold for molding the gear case. Consequently, the support shaft can be accurately and consistently provided to the gear case. Because the large-diameter part and the step part are embedded in the gear case, the resistance of the support shaft against pulling from the gear case can be enhanced.

Abstract: Each cross-section of the connector member assembling hole and the assembly main body 51a in a direction intersecting the insertion direction has a point-symmetrical circular shape with the insertion shaft center FC as the center. A pair of connector-side female terminals 57a, opposed to each other with the insertion shaft center FC as the center, is provided at the distal end side in the insertion direction of the assembly main body 51a, and a pair of brush-side male terminals, opposed to each other with the insertion shaft center FC as the center and to which the connector-side female terminals 57a are connected, is provided to a portion of the brush holder opposite to the connector member assembling hole. Therefore, it is possible to insert the connector member 50 into the gear case in the state of being rotated by 180 degrees about the insertion shaft center FC, and it is possible to cope with arrangement needs which are different by 180 degrees in a connection direction of the external connector, using one connector member 50.
Abstract translation: 连接器构件组装孔和组装主体51a在与插入方向相交的方向上的每个横截面具有以插入轴中心FC为中心的点对称圆形。 在组装主体51a的插入方向的前端侧设置有以插入轴中心FC为中心彼此相对的一对连接器侧阴端子57a，并且一对电刷侧阳极 以与插入轴中心FC为中心并且连接器侧阴端子57a连接的彼此相对的端子设置在电刷架的与连接器构件组装孔相对的部分。 因此，可以将连接器构件50以围绕插入轴中心FC旋转180度的状态插入到齿轮箱中，并且可以应对在连接方向上不同于180度的布置需要 的外部连接器，使用一个连接器构件50。

Abstract: A seal member is attached to a cover which occludes a gear case as a housing unit. The seal member is formed of elastomer and integrally formed with: a plate-shaped portion formed into a disc shape which covers the inner surface of the cover; an inner seal portion which is positioned on the inner peripheral edge of a through-hole, and comes into sliding contact with the outer peripheral surface of an output member; an outer seal portion which is positioned on the periphery of the cover, and comes into contact with the opening end of the housing unit; and anchor portions which latch onto the front surface of the cover via mounting holes provided to the cover. The boundary between the seal member and the cover extends only to the outside of the gear case, and does not extend to the inside of the gear case.

Abstract: On one side of a worm wheel (46) in an axial direction, first thinned portions (46e) recessed toward the other side of the worm wheel (46) in the axial direction are arranged. Further, on the one side of the worm wheel (46) in the axial direction, reinforcing portions (46h) reinforcing areas between the first thinned portions (46e) and tooth portions (45) of the worm wheel (46) are arranged. Therefore, it is possible to reduce a weight of the worm wheel (46) and to suppress occurrence of distortion of the tooth portions (45) by the first thinned portions (46e). In addition, it is possible to sufficiently increase the strength of the worm wheel (46) in the vicinity of the tooth portions (45) by the reinforcing portions (46h).

Abstract: Because the pressure angle β° (=12°) of teeth (47) of a worm wheel (46) is larger than the pressure angle α° (=11°) of teeth (45) of a worm (44), tips of the teeth (47) of the worm wheel (46) can be more tapered as compared with a case in which the pressure angle of the teeth of the worm and the pressure angle of the teeth of the worm wheel are the same angle (the conventional case). Thereby, it is possible to ensure non-contact of teeth, which had been variable in terms of contact and non-contact in the case of the conventional form, even if there has been non-uniformity in the teeth (47) of the worm wheel (46).

Abstract: A damper member (80) is provided between the worm wheel (39) and the output member (70), and elastically deformed by a relative rotation of the worm wheel (39) and the output member (70), a gap portion (SP) is provided between the worm wheel (39) and the output member (70), a portion (DP) bulged by elastic deformation of the damper member (80) is housed in the gap portion (SP), the portion (DP) bulged by elastic deformation of the damper member (80) does not push the output member (70) away from the worm wheel (39). Therefore, although it has the damper member (80), it is not necessary to fix the output member (70) so as to prevent the output member (70) from being moved in an axial direction of a support shaft by using a fixing member on the basis of a conventional manner, thereby making it possible to reduce the intensity of the support shaft, and consequently, it is possible to realize excellent shock resistance and silence, and cost reduction.
