Abstract
A heating apparatus for a vehicle with a simplified piping structure in a fluid pressure operating system, to a heat exchanger while preventing a pulsation of the operating fluid in the system from being directly transmitted to a cabin, thereby suppressing an occurrence of a noise in the cabin. A fluid pressure operating system includes an oil pump 12 rotated by an engine 21 and an actuator 20 operated by the operating fluid issued from the oil pump 12. A heat exchanger 39 is arranged between an outlet of the oil pump 12 and the actuator 20. Heat generated at the oil pump 12 in the fluid pressure operating system 11 is passed to the engine cooling water at the heat emitter and is used for heating the cabin.
