衝撃音が発生するおそれがある。However, since the closing speed of the self-closing sliding door is gradually accelerated by the force in the closing direction, if it is left as it is, the self-closing sliding door strongly collides with the door frame at the time of full closing, so that the door is closed. May be strongly pinched, or a loud impact noise may be generated.

れる。[0005] This type of air damper for a self-closing sliding door 1
Is mainly formed by an air cylinder 2 and a piston rod 3 fixed to the upper surface of the self-closing sliding door A, as shown in FIG. As shown by the chain line in the figure, when the piston rod 3 is fully closed, the iron suction piece 4 attached to the distal end of the piston rod 3 is brought into contact with the magnet 5 fixed to the door frame B, and is inserted into the air cylinder 2. It is plugged in. When the self-closing sliding door A is opened to the left in the drawing from this state, the piston rod 3 is attracted to the door frame B side by the coercive force of the attracting piece 4 and the magnet 5, and only the air cylinder 2 remains immobile. When the piston rod 3 is pulled out to the maximum, the suction piece 4 is forcibly separated from the magnet 5, and the air cylinder 2 and the piston rod 3 are moved together as shown by the solid line in FIG. Can be When the force to open the door by releasing the hand from the self-closing sliding door A is released, the self-closing sliding door A is closed to the right by the force in the closing direction, and after the suction piece 4 abuts on the magnet 5, the piston rod is closed. 3 is inserted into the air cylinder 2 and compresses the air in the air cylinder 2 and discharges the air little by little to the outside, so that the closing speed of the automatic closing sliding door A traveling in the closing direction is reduced.

音材１２によって消音されるようになっている。With respect to the air damper 1 for a self-closing sliding door having such a basic structure, Japanese Utility Model Publication No. 1-38228 discloses a method for silencing the sound of discharging air from the air cylinder 2. A proposal has been made. That is, as shown in FIGS. 6 and 7, an air outflow hole 7 is formed in the bracket 6 supporting the end of the air cylinder 2 on the air outflow side in the axial direction of the air cylinder 2. A needle valve 8 for adjusting the flow rate is screwed into the female screw part 10 with its male screw part 9 in the outflow hole 7,
A sound absorbing material 12 such as a sponge is filled in a discharge hole 11 for air discharge which communicates with the outside in a direction perpendicular to the air outflow hole 7, and an arc-shaped piece 13 is put on the outside of the sound absorbing material 12 to prevent extraction. doing. Then, the air flows out into the air cylinder 2 through the discharge hole 11 and the air outlet hole 7, performed by the flow rate adjusted by the needle valve 8, as muted I by the sound-absorbing material 12 Has become.

も必要であるという不都合がある。However, in the above-mentioned conventional example, the exhaust hole 11 is formed in the shape of a small-diameter circular hole, so that the sound deadening effect is not sufficiently exhibited, and the piston rod 3 is inserted into the air cylinder 2. However, there is still a problem that sound is still generated. Further, there is a disadvantage that a special arc-shaped piece 13 is required to prevent the sound absorbing material 12 from being pulled out, and a troublesome assembling operation is also required.

う不都合がある。As shown in FIG. 8, instead of the arc-shaped piece 13, a sound absorbing material 12 such as a sponge inserted into a discharge hole 11 is formed by wire work.
It has been proposed to suppress from the outside by the four suppressing portions 14a. However, in this configuration, when air is discharged 100,000 times or more, the sound absorbing material 12 suppressed only by the thin wire-shaped suppressing member 14a gradually protrudes from the gap between the discharging through hole 11 and the suppressing member 14a. There is a disadvantage that the sound absorbing material 12 eventually comes out.

As shown in FIG. 1, it is formed in a serrated shaft shape having the same cross-section in the axial direction with the cross section being substantially indented, and penetrating through the lead-out hole 25 a of the bracket 25. The serration shape may be selected from various types according to the design purpose, strength and the like. And in this embodiment,
The ratio of the outer diameter of the piston rod 23 to the inner diameter of the air cylinder 22 is larger than that of the conventional example, so that the air cylinder 22 is formed to have a larger diameter. Further, the outlet hole 25a is connected to the piston rod 2
3, the piston rod 23 is always supported coaxially with the air cylinder 22 by the outlet hole 25a. This piston rod 2
An annular seal body 40 made of an elastic member that performs an air compressing action is fitted in an annular groove 41 at an inner end portion (left side in FIG. 1) of 3. The annular groove 4 adjacent to the tip side of the seal body 40
2, the piston rod 23 comes into contact with the inner end face 25 b of the bracket 25 when the piston rod 23 is pulled out.
A stopper 43 for restricting the maximum pull-out position of No. 3 is fitted. The stopper 43 is formed of urethane foam, felt, or the like, is formed to have an outer diameter that can always slide on the inner surface of the air cylinder 22, and is impregnated with a lubricant such as grease. Therefore, this stopper 43
Functions to prevent the generation of an impact sound at the time of contact with the inner end surface of the bracket 25, impart lubricity to the air cylinder 22, and ensure dustproofness in the air cylinder 22.

Regulate position. At this time, the stopper 43 prevents the generation of an impact sound at the time of contact. In addition, the stopper 43 slides on the inner peripheral surface of the air cylinder 22 to provide a lubricating material impregnated to the air cylinder 22 to ensure lubricity or to secure dustproofness in the air cylinder 22. Works like that.
