PROBLEM TO BE SOLVED: To provide a tilt-down mechanism capable of making a seat cushion sink effectively even when a sinking space of the seat cushion is narrow.SOLUTION: A seat 1 comprises a tilt-down mechanism TD for making a seat cushion 3 sink toward a lower side by forward tilting movement of a seat back 2. The tilt-down mechanism TD comprises a drawing belt 5 which connects a rear part of the seat cushion 3 and a rear base FB on a floor F by a rotary shaft 3A, connects a front part of the seat cushion 3 and the floor F via a front link 4, and links the front link 4 and the seat back 2. The tilt-down mechanism TD is configured in such a manner that a movement in which the seat back 2 is reclined forward allows the drawing belt 5 to pull the front link 4 down toward a rear side, and a front part of the seat cushion 3 to sink toward a lower side around the rotary shaft 3A. |
