Abstract
The present invention comprises: a unit case; a damper which switches between the open state and the closed state of a flow path; a plurality of damper levers which have pins and rotatably support the damper with respect to the unit case; and a main lever which has guide grooves into which the pins are fitted, and rotates the damper levers by guiding pins through rotation around an axis, wherein the main lever has a main lever body having the guide groove formed therein, and a shaft part which rotatably supports the main lever body and is provided with a hook portion engaged with the unit case, and the shaft part has a higher toughness than the main lever body and is made of a material different from that of the unit case.
Claims4
An air conditioner for a vehicle which is installed in the vehicle, the air conditioner comprising:
- an evaporator that cools air;
- a heater core that heats the air;
- a unit case that accommodates the evaporator and the heater core and in which an air mixing space where the air supplied from the evaporator and the air supplied from the heater core are mixed with each other is defined and a plurality of flow paths through which the air mixed in the air mixing space flows are formed;
- a plurality of dampers that cause the plurality of flow paths to switch between an open state and a closed state;
- a plurality of damper levers that rotatably support the plurality of dampers with respect to the unit case and that include pins extending to be parallel to rotation axes of the dampers;
- and
- a main lever in which a guiding groove into which the pins are fitted is formed and that rotates around an axis to guide the pins and to rotate the damper levers,
- wherein the main lever includes
- a main lever main body in which the guiding groove is formed, and
- a shaft portion that is provided at a position of the axis, supports the main lever main body with respect to the unit case such that the main lever main body is rotatable around the axis, and is provided with a claw portion that is engaged with the unit case so as not to fall off from the unit case, and
- the shaft portion has a toughness higher than the main lever main body and is formed of a material different from the unit case.
