An electric power steering apparatus comprises a housing (22b) for housing rotatably a steering shaft (18) interlocked with a steering wheel (not shown), an electric motor (8a) which has a through hole (50) through which a screw member (53) is to be inserted and is attached to the housing (22b) the screw member (53) through the through hole (50) and a gear mechanism (57), (56), connected to the electric motor (8a) through a joint (55), for transmitting a torque of the electric motor (8a) to the steering shaft (18). The joint (55) is formed by a synthetic resin so as to detach the electric motor (8a) from the housing (22b) an impact force in an axial direction of the steering shaft (18). Even when a portion of a vehicle body and a mounting bracket, etc. belonging to the vehicle body are caught on the electric motor during the primary collision or secondary collision, it is possible to sufficiently absorb the impact force of the secondary collision.
