PROBLEM TO BE SOLVED: To provide a ventilation register device capable of reducing an interference sound discomfort for a user, by avoiding contact between mutual parts in opening-closing operation of a ventilation part.SOLUTION: A reciprocating movement range Z of a slide plate 17 in an operation mechanism 13 for operating opening-closing operation of an opening-closing plate for opening-closing the ventilation part of a body 10, is regulated by a pair of slide operation cushioning materials 38 (a first cushioning material) arranged on a flat surface 14a of the body 10, and the reciprocating movement of an operation knob 27 and the reciprocating movement of a cam follower are also regulated by its reciprocating movement range Z. A slide groove extension area (a first groove extension area) is also formed outside the reciprocating movement range of the operation knob 27 corresponding to the reciprocating movement range Z of the slide plate 17 in a slide groove, and a cam groove extension area (a second groove extension area) is formed outside the reciprocating movement range of the cam follower corresponding to the reciprocating movement range Z of the slide plate 17 in a cam groove. |
