PROBLEM TO BE SOLVED: To provide a damper opening/closing mechanism capable of stably initializing a stepping motor regardless of the direction of a damper lever, in the damper opening/closing mechanism for opening/closing a damper through the damper lever having a pin slidably fitted in a cam groove of a link plate.SOLUTION: In a damper opening/closing mechanism of a vehicular air conditioner, a pin 28 of a damper lever 26 is fitted in a cam groove 24 of a link plate 22 rotationally driven by a stepping motor, and a damper 19 is opened/closed through the damper lever 26 rotated by rotation of the link plate 22. One end section of the cam groove 24 for setting a reference position of the stepping motor is made to have a shape in which A and B are connected by a curved surface and/or a plane (connecting surface 32) which is in non-contact with an outer peripheral surface of the pin 28 when a point where the outer periphery of the pin 28 is brought into contact with one end face of the cam groove 24 is defined as A and a point where the outer periphery of the pin is brought into contact with a side wall surface 24A of the cam groove 24 is defined as B when the damper 19 is placed in a closed position.SELECTED DRAWING: Figure 3

    【課題】リンクプレートのカム溝に、ピンが摺動自在に嵌合されているダンパレバーを介してダンパを開閉するものにおいて、ダンパレバーの向きに関係なく、ステッピングモータを安定的にイニシャライズできるダンパ開閉機構を提供することを目的とする。【解決手段】ステッピングモータにより回転駆動されるリンクプレート22のカム溝24にダンパレバー26のピン28が嵌合され、リンクプレート22の回転により回動されるダンパレバー26を介してダンパ19を開閉する車両用空調装置のダンパ開閉機構にあって、ステッピングモータの基準位置出しを行うカム溝24の一端部が、ダンパ19を閉位置としたときにピン28の外周がカム溝24の一端面と接する点をA、カム溝24の側壁面24Aと接する点をBとしたとき、そのA,B点間がピン28の外周面に対して非接触となる曲面および/または平面(結び面32)で結ばれた形状とされている。【選択図】図3
