PROBLEM TO BE SOLVED: To obtain a register capable of preventing or effectively suppressing the breakage of a fin during the operation of an operation knob.SOLUTION: The minimum clearances between a part 52A on a vehicle chamber 16 side than a rotation axis 44L of a first fin portion 44 and second fin bodies 50A and 50B in an operation knob 52A are set to be narrower than the minimum clearances between the first fin portion 44 and the second fin bodies 50A and 50B. A tip end 52S on a vehicle cabin side of an operation knob 52 and a tip end 50S on the vehicle cabin side of the second fin body 50A above the tip end 52S are set to align positions in a fore-and-aft direction, in a regulating state in which the tip end 52S on the vehicle cabin side of the operation knob 52 is rotated to the opposite side to the second fin body 50A and the first fin portion 44 is regulated in rotations by a regulation mechanism portion.SELECTED DRAWING: Figure 2 |
