Abstract: The shutter device has a blade and a frame member which supports the blade in a rotatable manner. The device has a shaft arranged along the frame member, an actuator device for rotating the shaft, and a link member which opens and closes the blade by transmitting a rotational force of the shaft to the blade. The device has a calibration structure having a calibration member formed on the shaft and a calibration surface formed on the frame member. The calibration structure calibrates a rotational position of the shaft by coming into contact with the calibration member onto the calibration surface. The device further has a discharge structure which discharges foreign matters existing between the calibration member of the shaft and the calibration surface of the frame member.

Abstract: A vehicle heat exchange system includes a cooling heat exchanger provided in a cooling water circuit, a first air-conditioning heat exchanger as an evaporator in a heat pump system, a hydrothermal-medium heat exchanger as a refrigerant condenser in the heat pump system, a second air-conditioning heat exchanger, and an air conditioning passage in which the first air-conditioning heat exchanger and the second air-conditioning heat exchanger are disposed. A vehicle interior-exterior communication port is provided at a downstream side of the second air-conditioning heat exchanger in the air conditioning passage, to guide the air having passed through the second air-conditioning heat exchanger, to an outside of the vehicle interior. The cooling water for cooling the heating element flows through the second air-conditioning heat exchanger, and the air having passed through the second air-conditioning heat exchanger is discharged outside the vehicle interior through the vehicle interior-exterior communication port.
