Anti-reverse clutch

An anti-reverse clutch apparatus comprising:

• an input shaft, which is rotated by rotation force supplied to the input shaft and which is provided with a push handle projecting radially from the input shaft;
• an output shaft, which is mounted coaxially with the input shaft and is rotatable relative to the input shaft;
• a clutch housing including an internal gear formed along an internal circumferential surface of the clutch housing;
• and
• a locking block, which is mounted between the output shaft and the internal circumferential surface of the clutch housing, and rotatable together with the output shaft,
• wherein the locking block includes an external gear, which is formed along an external circumferential surface of the locking block to be engaged with the internal gear,
• wherein the locking block is linearly movable in a radial direction of the output shaft by a sloped surface structure formed between the push handle and the locking block so that the external gear is engaged with or disengaged from the internal gear when the push handle is rotated,
• wherein two lateral sides of an end portion of the push handle are provided with respective push portions, each of which is in a shape of a wedge having a sloped push surface on an external surface thereof, and
• wherein two lateral sides of an end portion of the locking block adjacent to the push handle are provided with respective slide portions, each of which is in a shape of a wedge having a sloped slide surface corresponding to a corresponding one of the sloped push surfaces.
