Document Type and Number:
Japanese Patent JP7231455
Kind Code:
B2
Abstract:
To provide a motion converting mechanism, a motor, and a wiper motor capable of improving durability while reducing occurrence of noise and wear.SOLUTION: A motion converting mechanism 13 includes a first gear 20 which rotates around a rotation axis L1 and has a first meshing part 22, and a second gear 30 which rotates around a rotation axis L2 parallel to the rotation axis L1 and has a second meshing part 32. The first gear 20 has a drum like shape. A first side face 21 has a pair of arc shaped recessed sections 21A recessed to the rotation axis L1. A second side face 31 has a rotation curved face around a rotation axis L2 and formed along the recessed sections 21A of the first side face 21. The first meshing part 22 has a first path 22A spirally formed in a circumferential direction of the rotation axis L1, and a second path 22B continued from the first path 22A and spirally formed with an opposite pitch to the first path 22A. The second meshing part 32 is magnetically coupled to the first meshing part 22 and has an arc shape in the circumferential direction of the second side face 31.SELECTED DRAWING: Figure 3
