PURPOSE: A lubrication structure of a clutch for a vehicle is provided to prevent wear and degradation caused by friction of a release fork hinge part by making lubricating action performed to a release fork. CONSTITUTION: A clutch comprises a clutch disk(6), a pressure plate(8) pressurizing the clutch disk and sticking the clutch disk fast to a flywheel(2), a diaphragm spring(10), a release bearing(12) pushing the diaphragm spring, and a clutch-operating apparatus pushing the release bearing according to the operation of a clutch pedal. The clutch-operating apparatus comprises a master cylinder producing hydraulic pressure according to pedal pressure of the clutch pedal, a release cylinder(20) straight moving a push rod(22) by the hydraulic pressure, and a release fork(24) transmitting the force pushing the push rod to the release bearing. The release fork is connected with the push rod and release bearing and forms a hinged part(26) to a side and transmits the pushing force of the push rod to the release bearing. The hemisphere shaped-hinged part is contacted to a hinged protrusion(30) fixed to a clutch housing. A lubrication device is formed to the hinged protrusion to prevent friction when the hinged part and hinged protrusion is contacted with and rotates.
