They are used in many places, and all of them have a structure in which air flows in and out as the piston shaft moves. This caused a peculiar sound to occur, especially when air was exhausted from the cylinder. This sound was particularly undesirable in places where silence was required. The present invention is a sound damping device that muffles this sound, and its structure is entirely made of rubber material, and has a mounting hole that tightly fits onto a part of the air cylinder, and a mounting hole that is connected to the mounting hole so that the air cylinder can enter and exit the air cylinder. A first ventilation hole that matches the hole, a ventilation chamber connected to the first ventilation hole and larger than the first ventilation hole, and a second ventilation hole connected to the ventilation chamber and smaller than the ventilation chamber. On the other hand, it is characterized in that a sound absorbing material is interposed in the first ventilation hole, the ventilation chamber, and the second ventilation hole.

ている。 As shown in FIGS. 2 and 3, the silencer 7 has a mounting hole 8 that tightly fits into the air flow control section 3.
When the silencer 7 is attached to the air flow control section 3, the air inlet/outlet hole 5 is connected to the mounting hole 8.
The first ventilation hole 9 provided at the same location, and the first
A ventilation chamber 10 connected to the ventilation hole 9 and larger than the first ventilation hole 9;
It is made of a rectangular rubber material and has a second ventilation hole 91 having approximately the same size. 11
are the first ventilation hole 9, the ventilation chamber 10, and the second ventilation hole 9.
In this embodiment, a polyurethane foam, a so-called sponge, is used.

第一通気孔９を通過する。 The silencer 7 configured as described above has the mounting hole 8
The air flow control part 3 of the air cylinder 1 is press-fitted into the air cylinder 1 to position the air inlet/outlet hole 5 above the first vent hole 9 of the silencer 7. At this time, since the silencer 7 is made of a rubber material, if the mounting hole 8 is made slightly narrower than the air flow control section 3, the air inlet/outlet hole 5 will be tightly fitted due to its elasticity.
All the air discharged from the air will pass through the first ventilation hole 9. In other words, all the air exhaust sound passes through the first ventilation hole 9.

ある等の実用的価値が大なるものである。 As mentioned above, the air cylinder 1 is equipped with a silencer 7.
When the air inlet/outlet is installed, the sound generated at the air inlet/outlet passes through the first ventilation hole 9 and is attenuated by the sound-absorbing material 11, and when it goes out into the wide space of the ventilation chamber 10, the sound is synergized with the effect of the sound-absorbing material 11. The sound is discharged from the second ventilation hole 91 in a state where the resonance sound absorption effect acts and the sound is further muffled. In this way, most of the sound generated in the air inlet/outlet hole 5 is muffled by the resonance sound absorbing effect in the ventilation chamber 10 and the sound absorbing effect by the sound absorbing material 11. In addition, since the entire structure is made of rubber material, the mounting hole 8 has elasticity and can be tightly fitted to the air flow control part to prevent air leakage. Since only a part of the air cylinder is tightly fitted to the outside, it is easy to attach and detach, which has great practical value.
