PURPOSE: A ratchet wheel apparatus is provided to enable a turning force to transfer in one way with a simple structure by omitting a spring inside. CONSTITUTION: A ratchet wheel apparatus(100) comprises a pawl(120) and a holding portion(140). The pawl is extended by being bent from an inner periphery of a driving shaft(110) towards a lengthwise driving shaft(130). The holding portion is formed on an outer periphery of the lengthwise driving shaft. The holding portion is connected to each pawl. The holding portion enables the pawl to be connected to both directions of a gear(142). The holding portion is closely located with a self-elasticity structure whereby a plurality of pawls is bent. The gear individually forms vertical surfaces(142a,142b) on both sides.
