A ratchet wheel for a tightener in the field of mechanics, which addresses the problems existing in conventional tighteners where the ratchet wheel tends to be shifted to offset or dislocate the reel. The ratchet wheel for the tightener includes a wheel body which is of a round-disk shape and has several ratchets along the edge thereof. Axial holes are set at the wheel body to pass the reel. Connecting parts are disposed at the ends of the axial holes to protrude vertically from the end face of the ratchet wheel. The connecting parts could be embedded onto the handle or support of the tightener. The ratchet wheel for the tightener is equipped with the advantages such as firm connection and high reliability.
