Description

上記課題を解決するために、本発明に係る駆動装置は、空気の流れを規制するドア部材（３５０）の駆動を行うための駆動装置であって、回転軸（ＭＸ）を有するモーター（Ｍ）と、棒状の部材であって、回転軸と共に回転する第１部材（１００）と、第１部材の少なくとも一部を外側から囲むように配置された第２部材（２００）と、第２部材の少なくとも一部を外側から囲むように配置された第３部材（３１０）と、回転軸の中心軸（ＣＡ）周りにおける第１部材の回転運動を、中心軸に沿った第２部材の直線運動に変化する第１変換機構（１１０，２１０）と、中心軸に沿った第２部材の直線運動を、中心軸周りにおける第３部材の回転運動に変換する第２変換機構（２３０，３１３）と、を備え、第３部材の回転運動に連動してドア部材の駆動が行われるように構成されており、第２変換機構は、第２部材の外周面から外方に向けて突出する駆動突起（２３０）と、第３部材の内周面（３４０）に螺旋状に形成された有底の溝であって、駆動突起を内部に受け入れる駆動溝（３１３）と、を有していることを特徴とする。 In order to solve the above-described problems, a drive device according to the present invention is a drive device for driving a door member (350) that restricts the flow of air, and includes a motor (M) having a rotating shaft (MX). A first member (100) that rotates with the rotating shaft, a second member (200) disposed so as to surround at least a part of the first member from the outside, and a second member The rotational movement of the first member around the central axis (CA) of the third member (310) arranged to surround at least a part from the outside and the central axis (CA) of the rotational axis is changed to the linear motion of the second member along the central axis. A first conversion mechanism (110, 210) that changes, a second conversion mechanism (230, 313) that converts a linear motion of the second member along the central axis into a rotational motion of the third member around the central axis, The door is interlocked with the rotational movement of the third member Are configured to drive the wood is carried out, the second conversion mechanism includes a drive projection that projects outward from the outer circumferential surface of the second member (230), the inner peripheral surface of the third member (340) And has a drive groove (313) for receiving a drive projection therein.
