<P>PROBLEM TO BE SOLVED: To provide a damping device, in which a valve can be moved by a large amount and a rotation range of a flap can be increased without increasing the rotating directional dimension of the flap and a case housing the flap. <P>SOLUTION: The damping device 30 includes: the case 31; a fluid filled space 37 filled with a viscous fluid; and the flap 45 provided in the fluid filled space and rotating around a rotary shaft 49. The damping device 30 also includes: an inner flow passage 52 formed in the flap, extending in a direction parallel with the rotary shaft, formed with inlets 57 and 58 in one of opening ends thereof, and formed with outlets 53 and 54 in the other opening end thereof; a valve 63 provided in the inner flow passage to open and close the inlets by moving in the direction parallel with the rotary shaft; and an urging member 69 provided in the inner fluid passage to move the valve by urging the valve toward a closing position, in which the inlets are closed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
