<p>PROBLEM TO BE SOLVED: To provide a register which reduces pressure loss during ventilation and ventilates focused spot wind.SOLUTION: A register is configured so that: a front fin 7 and a rear fin 41 are disposed in an orthogonal direction, a control knob 5 is slidable fitted to the front fin 7, a rear part of the control knob 5 engages to the rear fin 41, and the rear fin 41 is rotated and operated. On the rear part of the control knob 41, a fork-shaped engaging part 6 is provided so as to engage to the rear fin 41. On a fin body 42 of the rear fin 41, an engaging axis 43 to which the fork-shaped engaging part 6 can engage is provided, with a notch 44. The notch 44 is formed so that its width gradually becomes shorter from a rear part toward a front opening part. On a peripheral edge other than a rear edge and the front opening part in the notch 44, guide fins 47, 48 are provided.</p> |
