PURPOSE:To contrive smoothness of changes in the blowing out direction in such a way that a step is provided between the part which is formed in the gradual expanding shape in the downstream side of a rear guider, and the part which is formed in the straight line shape, and exfoliation of the flow which is absorbed to the straight line part of the rear guide. CONSTITUTION:A step 9e is provided between the part 9c which is formed in the gradual expanding shape in the downstream side of a rear guider 9 and the straight line part 9d as shown in the figure. Thus, in case where a flow control member 10 is turned from downward blowing condition to horizontal blowing condition, it hastens exfoliation of the flow which is adsorbed to the straight line part 9d of the rear guider 9, and the blowing out direction can be smoothly changed. |
