動力が(動く。Next, the operation of the air damper 1 in the assembled state with the above configuration will be explained. When the piston 5 moves in the extension direction, that is, in the direction shown in FIG. Therefore, the check valve 8 closes and both chambers a and b
are communicated only by orifice 7. Therefore, the air in the rear chamber on the right side flows into the front chamber a on the opposite side through the fine orifice 7 and the inside of the piston 5 and the screw tm2, so that the air flows into the front chamber a on the opposite side. The braking force (moves).

緩和される。On the other hand, when the piston 5 moves in the contraction direction, that is, to the left in FIG. , both chambers a and b are also communicated through a ventilation hole 9. Therefore, the air in the front chamber a passes through the orifice 7 and the vent hole 9, as well as inside the piston 5 and the cap 28, and is discharged all at once to the rear chamber on the opposite side, causing the piston 5 to move in the contraction direction. On the other hand, the Le1 power is relaxed.

When the glow box 3 is opened, it opens by its own weight, and in the closed position, there is a locking device (not shown).
Air damper 1
A mounting piece 31 protruding from the rear end of the cylinder 4 is pivotally attached to the side wall of the instrument panel 2, and an annular ring portion 32 at the rear end of the rod 6 is pivotally attached to the side surface of the glow box 3.
従って、グローボックス3が開く際には、ピストン5が
