摘要： To provide a power seat slide device having improved effects of reducing abnormal sound, a temperature increase, and so on in gear mechanisms and so on. Gear mechanisms 30 each include a case 310 in which a worm 320 and a worm wheel 330 are rotatably supported, the cases 310 are suspended from and supported by upper rails 12. The worms 320 are connected to and supported by a rotational force transmission shaft 220 of a drive mechanism 20, and the worm wheels 330 are screwed to and supported by slide screws 11a provided in lower rails 11. Further, the cases 310 are supported on the lower rails 11 via balls 340 which are rolling members. This structure stabilizes a slide operation of the cases 310 themselves and can further improve the effects of reducing abnormal sound and so on.

摘要： A damper has a simple structure yet exhibits appropriate damping force according to a relative displacement amount. The damper includes: a line-shaped member 32 wound around an outer peripheral surface of a piston 3 which makes a relative motion in a cylinder 2; and a viscous fluid which is made to adhere to the line-shaped member 32 and exhibits viscous damping force. The relative motion of the cylinder 2 and the piston 3 produces tension, and in the line-shaped member 32, as an amplitude is smaller, its contiguously wound portions each try to deform so as to twist along a circumferential direction of the line-shaped member 32 itself, and as the amplitude is larger, the contiguously wound portions more tend to try to deform as a unit. When the amplitude is small, frictional resistance decreases, resulting in the smooth motion of the piston 3, and appropriate damping force is obtained due to the viscous damping force of the viscous fluid. When the amplitude is large, as a result of the increased tendency that the contiguously wound portions of the line-shaped member 32 try to deform as a unit, friction damping force acts relatively greatly.
