CONSTITUTION: A winch shaft of a spare tire for a vehicle is composed of a driving unit(2a) to which a crank handle is inserted; a rotary unit(2b) integrated with the driving unit and combined with a chain wheel; a cam unit(2c) eccentric between the driving unit and the rotary unit and contacting with a pinion; a through-hole(2d) formed at the cam unit of the shaft; and a rolling member installed in the cam unit and projected outward by the through-hole of the cam unit to roll-contact with the pinion. The rolling member is a bearing(10).
