    摘要： A deceleration mechanism is provided with first and second gears, a first tooth part arranged in the first gear and extending spirally in an axial direction of the first gear, an engagement projected part arranged on the first tooth part, second tooth parts arranged on the second gear, and an engagement recessed part arranged between the adjacent second tooth parts. The engagement projected part is formed in an arc shape in a direction orthogonal to the axial direction of the first gear and has a curvature center eccentric from a rotation center of the first gear. The second tooth parts are inclined with respect to the axial direction of the first gear and arranged in a circumferential direction of the second gear. The engagement projected part is formed in an arc-shape in a direction orthogonal to the axial direction of the first gear and engaged with the engagement projected part.

    摘要： According to the present invention, one engagement protrusion part 31c having a spiral shape is provided in a pinion gear 31, a plurality of engagement recess parts 32d engaged with the engagement protrusion part 31c are provided in a helical gear 32, and the engagement protrusion part 31c and the engagement recess parts 32d are each formed to have an arc shape in a direction perpendicular to the axial direction of the pinion gear 31. As a result, the pinion gear 31 and the helical gear 32 can be configured in an arc-shaped protrusion/recess engagement structure that does not deteriorate the state of engagement therebetween. Also, by increasing the number of teeth on the helical gear 32 while keeping the number of teeth on the pinion gear 31 at one tooth, the difference in the number of teeth can be easily increased. Therefore, the deceleration ratio of a deceleration mechanism 30 can be increased without increasing the volume thereof.

    摘要： In a 4-pole, 6-slot, 18-segment electric motor, one forward winding coil (91) and two reverse winding coils (92, 93) are wound on each tooth (12). When the forward winding coils are formed of coils corresponding to a U phase, a V phase, and a W phase and the reverse winding coils are formed of coils corresponding to a "-U" phase, a "-V" phase, and a "-W" phase, the coils, which correspond to a U phase, a "-W" phase, a "-W" phase, a V phase, a "-U" phase, a "-U" phase, a W phase, a "-V" phase, and a "-V" phase, are electrically connected in this order between the adjacent segments. When the number of turns of the coils (91) corresponding to a U phase, a V phase, and a W phase is denoted by T1, the number of turns of the coils (92), which correspond to a "-U" phase, a "-V" phase, and a "-W" phase and first come into sliding contact with a brush, is denoted by T2, and the number of turns of the coils (93), which correspond to a "-U" phase, a "-V" phase, and a "-W" phase and later come into sliding contact with the brush, is denoted by T3, "T2>T1>T3" is satisfied.

    摘要： A motor case 21 is positioned to a gear case 31 in the diametrical direction by diametrically-positioning projection portions 72c of a brush holder 70 by causing the motor case 21 and the gear case 31 to face each other, and an axially-positioning projection portions 72e of the brush holder 70 are pressed from the axial direction of an armature shaft 24 by a pressing flange portion 21i, so that the brush holder 70 is positioned to the gear case 31 in the axial direction. Therefore, the size and weight of the rear wiper motor 10 can be reduced by avoiding enlargement of the coupling portion of the motor case 21 and the gear case 31, and since it is unnecessary to interpose the brush holder 70 in the coupling portion between the motor case 21 and the gear case 31, a sufficient seal performance can be obtained.
