A power assist suit includes a harness worn at least around hips of a wearer, an assist unit, a power unit, and a bearing roller. The assist unit includes an arm and a thigh-worn part. A rail is provided at a part of the arm in a longitudinal direction. The rail includes channel-shaped parts extending along the longitudinal direction. The thigh-worn part is connected to sliding movable parts or integrated with at least a portion of the sliding movable parts. The bearing roller is disposed between each of the channel-shaped parts in the rail and each of inner wall surfaces of the sliding movable parts facing the respective channel-shaped parts.

In a coupling structure for coupling a shaft to a universal joint yoke, an insertion portion of a shaft is passed through an insertion hole of a universal joint yoke. An outward protrusion of a distal end portion of the shaft faces a peripheral edge of a first opening of the insertion hole across a gap in an axial direction. A fixed portion that adjoins the insertion portion is fixed to a peripheral edge of a second opening of the insertion hole by welding. An engaging portion formed on an outer periphery of the insertion portion and an engaged portion formed in an inner periphery of the universal joint yoke, which defines the insertion hole, are engageable with each other in a rotational direction with a rotation permitting gap for phase adjustment.
