A power assist apparatus includes an electric motor, a speed reducer, an annular torque sensor, a housing in which the speed reducer and the torque sensor are arranged, and an annular center aligning bracket. The housing includes a first housing element and a second housing element, and one of the first housing element and the second housing element is made of a synthetic resin. The center aligning bracket is fixed to the one of the first housing element and the second housing element by insert molding such that the center aligning bracket is concentric to the one of the first housing element and the second housing element. The first housing element and the second housing element are joined such that the first housing element and the second housing element are engaged with each other in an axial direction of the torque sensor via the center aligning bracket.
