PROBLEM TO BE SOLVED: To provide a register in which leakage of wind from the periphery of a cylindrical frame, which easily occurs when a movable fin of a rotatable louver is closed, can be prevented.SOLUTION: A shaft part 82 of a ball joint 8 is supported slidably in an axial direction by a support part 11 provided in the center part in a retainer 1, and includes a coil spring 84 for energizing the shaft part 82 to an upstream side. The outer peripheral surface of a cylindrical frame 20 is provided in approximately non-contact with the retainer 1 or the inner peripheral surface of a bezel 9 fitted in the front of the retainer 1 through a small gap. When a movable fin 23 of a rotatable louver 2 closes a flow channel 15, the shaft part 82 of the ball joint 8 is caused to slide together with the cylindrical frame 20 to a downstream side with respect to the support part 11, the periphery of the cylindrical frame 20 approaches or comes into contact with the retainer 1 or the inner peripheral surface of the bezel 9 to close a gap of the periphery.SELECTED DRAWING: Figure 12 |
