PROBLEM TO BE SOLVED: To provide a wiper motor which can prevent shock from working largely on a mount. SOLUTION: A gear cover 40 made in the shape of a roughly T-form plate is fastened to cover a warm gear speed reducer 22 and a clamp device 25, in the opening 21 of a wiper motor 1 used for a rear wiper device. The first mount 43 and the second mount 44 in the relation of confronting each other across a wiper shaft 31 are made at both ends of the first band-shaped part 41 of the T-shaped longitudinal member of the gear cover 40. The third mount 45 in the relation of confronting the second mount 44 across the rotating shaft 12 of an electric motor 11 is made at the tip of the second band-shaped part 42 crossing in T shape the first band-shaped part 41. The center of gravity G of the motor 10 and the gear 20 is arranged within a triangular area constituted of the first mount 43, the second mount 44, and the third mount 45.
