Abstract
A damper device may include a frame, a baffle turnably supported on the frame for opening and closing a passage through which fluid is passed, and a drive unit for turnably driving the baffle. The drive unit may include an output member whose tip end side structures a slide mechanism together with the baffle, and a driving part which causes the output member to linearly advance and retreat to and from the baffle. The slide mechanism includes a groove formed in one of a tip end side of the output member and the baffle so that the groove is extended to move the baffle, and a slider part provided in the other so that the slider part is fitted into the groove, and the groove is formed in which at least one of both end portions of the groove is formed in an open end.

- a frame;
- a baffle which is turnably supported on the frame for opening and closing a passage through which fluid is passed;
- a drive unit for turnably driving the baffle comprises:
- an output member whose tip end side structures a slide mechanism together with the baffle;
- and
- a driving part which causes the output member to linearly advance and retreat to and from the baffle;
- wherein the slide mechanism comprises:
- a pair of grooves which is formed in the baffle so that the grooves are extended to move the baffle;
- and
- slider parts which are protruded from both faces on a tip end side of the output member so that the tip end side of the output member is disposed between the grooves and the slider parts are fitted into the grooves;
- and
- wherein the grooves are respectively formed with open ends which are opened in a same direction on at least one same end of the grooves so that the slider parts fit through the open ends of the grooves.
