機装置。 In a vehicle warm-up device in which an exhaust brake valve disposed in an exhaust pipe of an engine is used as a warm-up valve, the rotation axis of the exhaust brake valve is disposed at a position offset from the axis of the exhaust pipe. At the same time, a biasing member is interposed between the output rod of the actuator that operates the exhaust brake valve and the rotating shaft of the exhaust brake valve, and during warm-up operation, the biasing force of the biasing member is applied to the exhaust brake valve. The exhaust brake valve is configured to be rotated and energized to a fully closed state within the exhaust pipe, and a stopper mechanism is provided on the output rod, so that when the actuator is actuated, the output of the actuator is applied to the exhaust brake valve via the output rod. A vehicle warm-up device characterized in that the vehicle warm-up device is configured such that no power is transmitted to the rotation shaft of the vehicle.
