Abstract
A valve hole punching apparatus for a vehicle wheel wherein the punch and the bill punching a valve hole in the wheel wall can be adjusted in inclination. In such an apparatus, a wheel into which a valve hole is to be punched is brought to the punching position with its axis maintained in a vertical position. The wheel portion to be punched is punched out by the inclined punch and the bill positioned at a right angle. As a result, handling of the wheel is very easy and punching can be done very smoothly.
