PURPOSE: An apparatus for measuring abrasion of a valve seat of a vehicle engine is provided to precisely measure abrasion of the valve seat by integrally forming a master valve with a gauge. CONSTITUTION: An abrasion measurement apparatus for a valve seat includes a supporter(13) making contact with a head surface(11) of an engine. A probe pipe(15) is fixed to the supporter(13). A probe rod(17) is installed in the probe pipe(15). A master valve(19) is fixed to one end of the probe rod(17) in such a manner that the master valve(19) is elastically supported against the supporter(13). A gauge(21) is fixed to the other end of the probe rod(17). The supporter(13) has a bridge shape and is placed on a head surface(11) of an engine. A spring(21) is installed between the master valve(19) and a lower portion of the supporter.
