In various other devices, in order to prevent leakage of fluids such as air, water, oil, etc., a packing mounting groove is provided at a required position of the device, and an O-ring made of synthetic resin, synthetic rubber, etc. in the packing mounting groove. A ring-shaped packing with various cross-sectional shapes is attached depending on its intended use, but in equipment requiring such packing (hereinafter referred to as the "attached member to be packed"), the packing mounting groove is out of reach. In case of being located at or in a packing mounting member having a caliber that cannot be accessed, a dedicated jig for mounting the packing was used.

Even if the packing is installed in the packing mounting groove, the packing itself has a diameter larger than the diameter of the member to be packed and has elasticity, so position the packing to the packing mounting groove in the back of the member to be packed. It is very troublesome to do, it takes time and labor, and if this work can be done visually, it is less difficult, but when installing in a location that is not visible, feel the distance to the packing installation groove. However, the jig must be felt by the operator's feeling and requires a considerable amount of skill.Because the jig has a sharp tip, it causes defects such as damage to the packing during the mounting process. And which, effort has been demanded that the jig for attaching the easy easy packing without requiring time.

In view of the problem that conventional jigs cannot be easily installed, a packing holding groove is formed on the outer periphery of the disk, and a recess is formed from a predetermined portion on the packing holding groove toward the center of the disk to form a packing holding portion. , A supporting rod is provided in the axial direction of the packing holding part, and the fulcrum part of the operating rod having a packing locking part at the tip of the supporting rod is swingable and can be moved back and forth in the axial direction of the operating rod. The packing is attached to the packing holding groove by operating the packing locking part with the operating rod so that part of the packing installed in the packing holding groove is bent into the recess to reduce the packing diameter and insert the packing into the member to be packed. Not only is it easy, but by releasing the packing that has been bent into the recess, it is installed in the packing mounting groove by the elastic restoring force of the packing, and the tongue piece projects on the peripheral edge of the packing holding part. By sliding the piece against the inner wall of the packing mounting member, the position of the packing mounting groove can be accurately confirmed by the feeling that it falls into the packing mounting groove when the tongue piece is located in the packing mounting groove, and the above problem is solved. It is a spoiler.

る。In summary, according to the present invention, the packing holding groove 5 is formed on the outer periphery of the disk, and the recess 6 is formed from a predetermined portion on the packing holding groove 5 toward the center of the disk to form the packing holding portion 2. A support rod 3 is provided in the axial direction of the packing holding portion 2, and a packing locking portion 20 is provided at the tip of the support rod 3.
Since the fulcrum portion 18 of the operating rod 4 provided with is supported so as to be swingable and movable back and forth in the axial direction of the operating rod 4, the packing P corresponding to the packing mounting groove G of the packing mounting member W is packed. By mounting the packing P in the packing holding groove 5 of the holding part 2 and swinging the operating rod 4 so that the packing P corresponding to the position of the recess 6 is locked in the packing locking part 20 and pulled inward of the recess 6. , Packing P to packing holding section 2
The packing mounting member W is mounted so as to have a diameter smaller than the diameter of the packing mounting member W, and the packing mounting groove G of the packing mounting member W is located within a reachable range. Even when mounting on a packing mounting member W with a diameter that cannot be reached, the packing holding portion 2 with the packing P mounted thereon is supported by the support rod 3 to a position where the packing mounting groove G inside the packing mounting member W exists. It can be easily and smoothly inserted, and when mounting the packing P in the packing mounting groove G, the operating rod 4 is swung so that the packing P bent in the recess 6 is loosened, and the operating rod 4 is inserted. By pulling the packing P toward the base end side, the packing locking portion 20 in which a part of the packing P is bent can be disengaged from the packing P, whereby the packing P in a deformed state has its elastic force. It can be restored to a ring shape, and the elastic restoring force allows the packing P to be mounted in the packing mounting groove G, and the packing P can be easily and easily mounted without any difficulty. Since the jig according to the present invention does not have an acute-angled portion that damages the packing P as in the conventional case, the packing P can be attached without damage.

When the tongue piece 10 is inserted into the to-be-packed attachment member W, the tongue piece 10 is slidably brought into contact with the inner wall I of the to-be-packed attachment member W.
The position of the packing mounting groove G can be accurately confirmed by the feeling that it falls into the packing mounting groove G when it is located in the packing mounting groove G. Especially, even when the position of the packing mounting groove G cannot be visually recognized from the outside. Since the position of the packing mounting groove G can be easily confirmed, and the protruding position of the tongue piece 10 corresponds to the edge of the packing holding groove 5, there is no problem in mounting the packing P in the packing holding groove 5.

る。Further, since the fulcrum portion 18 of the operating rod 4 is supported at its end portion by the support shaft rod 22 which contacts the inner wall I of the member W to be packed, the support shaft rod 22 is inserted when the packing holding portion 2 is inserted. Can always be brought into contact with the inner wall I, so that the packing holding portion 2 can be always held perpendicular to the axis of the packing mounting member W, and at the time of mounting the packing P in the packing mounting groove G, the packing P The packing mounting groove G can be positioned on the same plane of the packing holding portion 2 in which the packing is mounted, and the packing P can be accurately mounted without failure.

く、作業上の手間を省くことが出来る。A packing holding groove 5 is formed on the outer periphery of the elliptical disk, and a recess 6 is formed from a predetermined portion on the packing holding groove 5 toward the center of the elliptical disk to form the packing holding portion 2
Since the end portion of the packing holding portion 2 in the long axis direction is projected more than the packing holding portion 2 formed of a disk, the tongue piece 10 and the end portion are attached to the packing holding member by the end portion. A spindle rod whose length is set so as to contact the inner wall I of W
Since the packing holding portion 2 does not need to be provided with the tongue piece 10 because it plays the same role as both of the two, the manufacturing process of the packing mounting jig 1 can be facilitated, and moreover, the spindle rod 22 is mounted on the packing mounted member. There is no need to replace it so as to correspond to the diameter of W, and it is possible to save the labor for work.
