By allowing the front of the cup 200 and the door 700 to be in close contact with the vertical, it is possible to reduce the torque applied to the piston 424.

Accordingly, the inside of the case 422 may be formed to be hollow while being inclined by a corresponding angle so that the piston 424 may be inserted obliquely downward to move forward and backward.

In addition, a stroke adjusting means (not shown) may be further provided on the rear surface (left side in FIG. 3) of the case 422. Although not shown in detail, the stroke adjusting means is formed in a screw shape and is fastened to the rear of the case 422 to be inserted into the case 422 according to the rotational operation of the user, thereby the stroke of the piston 424. Can be adjusted.

On the other hand, the coupling part 440 protruding to the side (right side) is formed on one side (right side in Figure 2) of the case 422.

The coupling part 440 is coupled to the upper surface of the arm 100 to fix the damper assembly 400, and when viewed from above so as to be stably contacted with the upper surface of the arm 100. It would be desirable to have a rectangular shape. In more detail, the coupling part 440 is coupled to the body upper surface 120 ′ of the arm 100.

The coupling part 440 is laterally (right) from one side of the case 422, more specifically, from an upper end of the attachment surface 422 ′ of the case 422, which is in surface contact with the body side 120 ″. Therefore, when the damper assembly 400 is mounted, the bottom surface of the coupling part 440 and the attachment surface 422 'of the case 422 are the body upper surface 120' and the body side surface 120 ". The damper assembly 400 is mounted on the edge of the body 120 at the same time.

The coupling part 440 is provided with a removal groove 445 for removing the restraining member 480 to be described below. That is, as shown, the rear end of the seating portion 444 is formed with a recessed groove 445 of a predetermined size is recessed downward. Therefore, when the restraining member 480 to be described below is mounted to the damper assembly 400, and then the restraining member 480 is to be removed, a restraining member 480 may be lifted by inserting a driver into the stripping groove 445. do.

On the other hand, the coupling member 460 is formed on the lower surface of the coupling portion 440. The coupling member 460 may be inserted into the mounting hole 124 of the body 120, and may be engaged with the inner end (tip) of the mounting hole 124 to fix the damper assembly 400. It consists of hooks in the shape of '』.

In more detail, the coupling member 460 extends downwardly from the bottom of the coupling portion 440 and the front portion from the lower end of the extension portion 462 (left in FIGS. 3 and 6). It consists of a locking portion 464 that is vertically bent to extend.

In addition, the vertical length of the extension part 462 has a size corresponding to the thickness of the body upper surface (120 '). That is, the size of the upper and lower spaces between the bottom surface of the coupling part 440 and the upper surface of the locking part 464 corresponds to the size of the body upper surface 120 ′.

Therefore, when the damper assembly 400 is fastened to the body 120, the damper assembly 400 corresponds to the front end of the mounting hole 124 in the space between the bottom surface of the coupling part 440 and the locking part 464. The body upper surface 120 ′ is positioned.

As such, when the coupling member 460 is fitted to the front end of the mounting hole 124, the damper assembly 400 is fixed to the body 120 so as not to flow up and down.

Support pieces 470 are formed at both ends of the rear left and right (front and rear in FIG. 3) of the coupling member 460. That is, the pair of support pieces 470 protrude downward from the left and right bottom surfaces of the opening 442. The pair of support pieces 470 are spaced apart from each other by a predetermined distance, and the gap formed by the pair of support pieces 470 corresponds to the left and right lengths of the mounting holes 124. Therefore, when the damper assembly 400 is mounted to the body 120, the pair of support pieces 470 are inserted into the mounting hole 124 to block the left and right movement of the damper assembly 400.

On the other hand, the support piece 470 supports the support part 484 of the restraining member 480 to be described below. That is, the protruding support part 487 of the support part 484 hangs and fixed to the lower end of the support piece 470.

That is, the support piece 470 is formed in a relatively first half, the engaging support portion 472 for supporting the support portion 484 of the restraining member 480 to be described below, and the damper assembly 400 is the body ( When mounted to the 120 is made of a guide support portion 474 sliding sliding contact with the body upper surface (120 ').

The locking support 472 is formed in the first half of the support piece 470, as shown, the upper and lower lengths are at least greater than the thickness of the body upper surface 120 ', of the restraining member 480 to be described below The support 484 has a size corresponding to the height.

The guide support part 474 is a part formed at the rear part of the support piece 470 and is formed to have a size smaller than the height of the locking support part 472. Accordingly, the lower end of the guide supporter 474 is in contact with the upper body 120 'temporarily when the damper assembly 400 is mounted on the body 120.

As described above, when the front and rear heights of the support piece 470 are different from each other, when the damper assembly 400 is mounted on the body 120, the rear end of the support piece 470 is attached to the body upper surface 120 ′. This is to prevent interference.

Temporary assembling grooves 476 are further formed in the support piece 470. That is, on the surface where the pair of support pieces 470 face each other, the provisional assembling groove 476 as shown in FIG. 6 is formed long before and after. The provisional groove 476 may be formed both before and after the pair, or may be formed only in one. The temporary assembly groove 476 is a part in which the protrusion support part 487 of the restraining member 480 to be described below is temporarily accommodated. That is, when assembling the damper assembly 400, the restraining member 480 to be described below will be assembled in a state where the protruding support portion 487 of the restraining member 480 is accommodated in the temporary assembly groove 476. The restraining member 480 is fixed.

Meanwhile, a constraining member 480 is inserted into the opening 442 formed in the coupling portion 440 of the damper assembly 400, and the fixing of the damper assembly 400 is firmly fixed by the constraining member 480. Done.

The support part 484 is formed to have a size corresponding to the front and rear lengths of the opening part 442. Therefore, the rear end of the support part 484 is in contact with the rear end of the mounting hole 124 of the body 120, the front end is in contact with the rear end of the coupling member 460.

In this case, deformation of the coupling member 460 is prevented by the support 484, and the damper assembly 400 is not separated from the opening 442.

The pair of supports 484 are different from each other in the length of the upper and lower as shown. Since the thickness of the coupling portion 440 gradually decreases toward the right side, the length of the pair of support portions 484 also differs from each other, so that the pair of support portions 484 are on the right side (Fig. 4). The one on the left side is relatively shorter in length than the one on the left (right in FIG. 4).

In more detail, the pair of support parts 484 may extend from the bottom left and right side ends of the top plate 482 downwardly to the left and right sides of the extended support part 486 and the lower end of the extended support part 486. Protruding protrusion 487. In addition, the protrusion supporting portion 487 is formed to gradually decrease in thickness toward the lower side as shown, so that the restraining member 480 is easily inserted into the opening 442. Accordingly, when the restraint member 480 is completely inserted and mounted, the hook-shaped protruding support portion 487 formed on the support portion 484 may be engaged with the lower end of the locking support portion 472 of the support piece 470. .

Therefore, as shown in FIG. 7, in the state where the restraining member 480 is completely inserted into the opening 442, the left end of the support part 484 is rearward of the coupling member 460 (in FIG. 7).
