PURPOSE: A clutch of a vehicle is provided to radiate frictional heat between a clutch disk and a pressure plate assembly by modifying the structure of the clutch, and to lengthen a life span by preventing the disk and the pressure plate assembly from being damaged. CONSTITUTION: A clutch for a vehicle is composed of a disk(30) friction-contacted to a flywheel(2) intermittently to transmit rotational force from the flywheel to a power shaft(1) of a transmission; a pressure plate assembly(40) of a clutch cover contacting to the flywheel by pressing the disk; and a diaphragm spring(5) operating the pressure plate assembly according to operation of a pedal. Plural blades(302) are protruded radially in a disk hub(301) to blow in rotating the disk. Plural vent holes are formed radially in the pressure plate assembly to discharge air. Frictional heat between the disk and the pressure plate assembly is discharged efficiently with blowing by blades in rotating the disk, and the life span is extended with preventing the disk and the pressure plate assembly from being damaged.
