PROBLEM TO BE SOLVED: To provide a fixing structure of a wheel for a carrier for transportation having s simple configuration and capable of realizing its design easily. SOLUTION: This wheel fixing structure is constituted in such a way that a shaft rod 3 is provided in close proximity to a wheel part 2 of a bottom face part of a travelling body 1 so as to turn in the bottom face part thereof, a protrusion locking part preventing the turn of the wheel part is provided on the shaft rod against protrusion and energization so as to protrude and sink freely, the wheel part is locked in a lock condition when the protrusion locking part is positioned in a condition opposing to the wheel part, and the wheel part becomes a free condition when the protrusion locking part is turned and retracted from the wheel part by turning the shaft rod from the lock condition. Two bodies of the protrusion locking parts are provided in parallel at a predetermined interval in the direction of turn of the wheel part, and the wheel part is provided between two bodies of the protrusion locking parts so as to lock it in a turn impossible condition. The two bodies of the protrusion locking parts allow the turn and travel of the wheel part from its outer side and locking between the protrusion locking parts by sinking and moving, and the wheel part locked between the protrusion locking parts is disengaged to prevent the turn and travel to the outer side of the protrusion locking parts.
