To provide a motor and a power window motor which can prevent unwanted rotation of a turning shaft, and moreover can be driven smoothly.

In this power window motor 10, since a pressure-contact surface 56 of a pressure-contact member 50 to be placed in the pressure-contact with a braking surface 66 of a braking plate 64 is formed as a curved surface which is projected toward external side, if the axial direction of the pressure-contact member 50 is tilted together with a shaft 16, the angled part or the like of the pressure-contact member 50 will not be brought into contact with the braking surface 66 and only a small contact area is reduced for the braking surface 66. Therefore, even in a state of the axial direction of the pressure-contact member 50 being tilted, this power window motor 10 can be driven smoothly.
