PROBLEM TO BE SOLVED: To provide a louver structure capable of preventing the generation of noise.SOLUTION: If an operation knob 15 is rotated about a first shaft core O1 integrally with a first fin 11, the first fin 11 is interlocking-rotated about the first shaft core O1, and if the operation knob 15 is slid to the first fin 11, one second fin 12 is interlocking-rotated around a second shaft core 02, and second fins 12 other than the one second fin 12 are interlocking-rotated around the second shaft core 02. Arm portions 16A and 16B are formed in a generally semicircular shape projecting in a direction corresponding to a shaft core direction J of an engaging shaft 13. A constriction 20 is provided at an intermediate portion in a longitudinal direction of the engaging shaft 13, and curved surfaces of outer peripheral surfaces having generally semicircular cross sections of the arm portions 16A and 16B engaged with and abut on the constriction 20.
【課題】異音の発生を防止することができるルーバー構造を提供する。【解決手段】操作ノブ15を第1フィン11と一体に第1軸芯O1周りに回転させると、第1フィン11が前記第1軸芯O1周りに連動回転し、操作ノブ15を第1フィン11に対してスライド移動させると、一つの第2フィン12が第2軸芯02周りに連動回転するとともに、一つの第2フィン12以外の第2フィン12が第2軸芯02周りに連動回転し、アーム部16A,16Bは、係合軸13の軸芯方向Jに対応する方向に凸の略半円形状に形成され、係合軸13の長手方向中間部にくびれ部20が設けられ、アーム部16A,16Bの断面略半円形状の外周面の曲面がくびれ部20に係合当接する。【選択図】図2
