To provide a wiper motor capable of maintaining an excellent engaging state between an oscillating member and a gear member and miniaturizing the device.
In this wiper motor 90, an oscillation center shaft 140 of a sector gear 132 and an output shaft 12 are connected by a holding lever 138 provided on one side in a thickness direction of the sector gear 132, and thereby a pitch between the oscillation center shaft 140 and the output shaft 12 is maintained. Both sides in the thickness direction in a tooth part 136 of the sector gear 132 are held by the holding lever 138 on the one side in the thickness direction and a connecting wall 35 of a gear member 28 on the other side, and thereby an engaging margin of a gear tooth 136 and the tooth part 34 along the thickness direction of the sector gear 132 is maintained, and an excellent engaging state of the gear tooth 136 and the tooth part 34 is maintained. The sector gear 132 and the output shaft 12 are connected by the single holding lever 138 to miniaturize the whole constitution of the device.
