Abstract

An air mixing damper, which is displaceable in a direction substantially perpendicular to an air flow direction, is disposed between an evaporator and a heater core in a casing that constitutes a vehicular air conditioner. In the air mixing damper, a plurality of ribs are formed so as to project on a side of a dividing wall that divides an air flow passage, and rack gears, which are enmeshed with a shaft, are formed on an inner circumferential surface on the opposite side thereof. In addition, when the air mixing damper is assembled in the casing, in a condition in which the ribs are in abutment against a sealing surface of the dividing wall, pinion gears of the shaft are enmeshed with the rack gears, whereby jostling of the air mixing damper is prevented.

Dependent claims

A vehicular air conditioner including a casing having an air flow passage in an interior thereof, and a slide mechanism disposed movably in the interior of the casing, for switching a communication state of the air flow passage by moving in a direction to block the air flow passage,

the casing being formed in a dividable fashion in a lateral direction perpendicular to a displacement direction of the slide mechanism,
the casing comprising:
a guide member that engages with the slide mechanism for guiding the slide mechanism;
and
a seat section that abuts against a downstream side of the slide mechanism for blocking communication between upstream and downstream sides of the air flow passage;
and
the slide mechanism comprising:
a door main body that blocks the air flow passage by abutment against the seat section;
a shaft disposed rotatably in the casing and which is disposed on an upstream side of the door main body for thereby driving the door main body;
and
an engagement member, which is disposed on a lateral end portion on the door main body, and is engaged with the guide member,
wherein at least one of the guide member and the engagement member includes a correcting member for correcting an inclination of the door main body toward a seal member to a proper position.
