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.
