A load-relieving apparatus includes a wire cable 36 with a free end and a fixed end opposite to the free end, a locking part 361 being attached to the free end, a winding part 334 configured to wind the wire cable 36 from a fixed-end side thereof, a pulley 335 interposed between the winding part 334 and the locking part 361, and configured to stretch the wire cable therebetween, and a cover 336 with a through hole 338H formed therein through which the wire cable 36 is inserted, the cover 336 being interposed between the locking part 361 and the pulley 335, and formed so as to cover at least a part of the pulley 335. Further, the through hole 338H is configured so that a relative position of the through hole 338H with respect to a rotation axis of the pulley 335 changes.
