PROBLEM TO BE SOLVED: To provide a cross-flow fan device capable of performing even air blowing by stabilizing an airflow and also capable of suppressing generation of abnormal noise.SOLUTION: In a configuration in which width in the longitudinal direction of an air inflow part of a cross-flow fan 11 opposing to suction ports 10a, 10b is configured to be larger than the suction port, or in which the suction ports are arranged being off-set by a predetermined amount with respect to the longitudinal direction of the cross-flow fan, regarding the cross-flow fan, air inflow restriction means (a cylindrical part 20, a covering body 21, a connection shaft 25, restriction members 105a, 105b, 106a, 106b) is provided for restricting air flowing in a range deviating from the width of the suction ports. 【課題】空気流を安定させて均一な送風を行うことができ、異音の発生も抑制することのできるクロスフローファン装置を提供する。【解決手段】吸込口１０ａ、１０ｂに対向するクロスフローファン１１の空気流入部の長手方向の幅が当該吸込口より大きく構成され、または吸込口がクロスフローファンの長手方向に対して所定量だけオフセットして配置されている構成において、クロスフローファンについて、吸込口の幅から外れる範囲に空気が流入することを制限する空気流入制限手段（円筒部２０、覆体２１、連結軸２５、制限部材１０５ａ、１０５ｂ，１０６ａ、１０６ｂ）が設けられている。【選択図】図２
