An example of the use of a ring is shown, with a C ring 31 and various plugs 34
There is a problem that the C-ring 31 suddenly drops (falls off) as shown by an arrow A when it is attached to the shaft portion 32 such as and is inserted into the relatively deep hole 33 (while 31a is falling off). Some C

Mounted on the C-ring 31 and sealed with the C-ring 31 and used for a predetermined period of time. In some cases, as shown by reference numeral 31b in the figure, the holes 33 may remain at the bottom of the hole 33. In this case, it takes time and trouble to remove the C ring 31b, which not only reduces workability but also may damage the inner surface of the hole 33 when a rod-shaped removal jig is used.

生ずる虞があった。Therefore, in order to prevent such drop-off, it has been conventionally performed to make the inner diameter of the C ring 31 slightly smaller than the outer diameter of the shaft portion 32. This prevents the C-ring 31 from falling off, but in use, the C-ring 31 is compressed in the axial direction (thickness direction) and the inner diameter is reduced.
Since it bites into the shaft portion 32, a new problem arises that it becomes difficult to remove the C-ring 31 from the shaft portion 32 during repair, inspection, or replacement after that, and further, when removing, the shaft portion 32 ───
In particular, another problem that the stepped surface 36 important for sealing may be damaged may occur.

In the plan view of FIG. 2, the perspective view of the parts of FIG. 3, and the enlarged cross-sectional view of the main part of FIG. 4, 1 is a metal ring main body having a C-shaped cross section having an opening groove 3 on the inner circumference 2 side. Reference numeral 4 denotes a metal linear spring which is internally provided in the ring body 1 and has portions 5 ... Which partially project from the opening groove 3 in the inner diameter direction. In the illustrated example, the overall shape of the linear spring 4 is a U-shape, and both corners 6 and 6 and both leg tips 7 and 7 are
(Conversely) it is assembled so as to be located inside the ring body 1.

In particular, this opening width dimension S tends to decrease in a used state (sealed state), but the wire diameter of the linear spring 4 is set to be small so that the linear spring 4 is not caught in such a case. It is desirable to set to. 2 to 4
Indicates a free state (unattached state), and the distance W between the parallel legs of the linear spring 4 is larger than the inner diameter D i of the ring body 1.

The injector, various plugs, various sensors, and the like of the engine are externally fitted to the shaft portion 12 of the shaft member 11. At this time, the portion 5 that is internally provided in the ring body 1 and partially protrudes from the opening groove 3 is in close contact with the mounted shaft portion 12 and prevents the ring body 1 from moving in the axial direction of the shaft portion 12.

The shaft member 11 is inserted until the C ring 10 comes into contact with 14a, and the ring body 1 of the C ring 10 is compressed (in the axial direction) between the stepped portion 11a of the shaft member 11 and the stepped portion 14a. Then, a sealing action is performed (see FIG. 9). In other words, the stepped portion 11
a and 14a are the sealed surfaces.

ない。More specifically, the C ring 10 in the free state shown in FIGS. 6 and 2 and 4 is provided with the shaft portion 12 of the shaft member 11.
If the elastic spring is deformable, the projecting portions 5 of the elastically deformable linear springs 4 are, as shown in FIGS. 8 and 5,
It is elastically deformed, and due to its elastic urging forces F and F ', it comes into close contact with the outer peripheral surface of the shaft portion 12 and does not move in the axial direction of the shaft portion 12 (due to frictional resistance). In this state (as is clear from FIG. 8), the ring body 1 engages with the linear spring 4 in the opening groove 3, and the ring body 1 naturally does not move in the axial direction.

を防止できる。つまり、脱落防止機能を具備している。Therefore, as shown in FIGS. 1, 5, 7 and 8, immediately before the shaft portion 12 is inserted into the (deep) hole 14 from above, the C ring 10 is abruptly removed from the shaft portion 12. It can be prevented from falling off. In other words, it has a fall-out prevention function.

が望ましい。By the way, as shown in FIG. 4 to FIG.
The outer diameter of 12 is D 1, and the inner diameter of the ring mounting portion of hole 14 is D
2 and the inner and outer diameters of the ring body 1 are D i and D O , respectively, it is desirable to set D i > D 1 and D O <D 2 .

るためである。The reason is that the work of mounting the C-ring 10 on the shaft portion 12 can be carried out lightly and smoothly, and as shown in FIG. 7, it can be carried out lightly and smoothly when it is inserted into the hole 14.
Furthermore, the C-ring 10 can be smoothly removed from the shaft portion 12 for repair or replacement (with the shaft portion 12 pulled out from the hole 14 and disassembled).

─ In the state where the ring body 1 is crushed, the inner diameter D i of the ring body 1 is set to be larger than the shaft outer diameter D 1 , and the outer diameter D O is smaller than the hole inner diameter D 2. Is desirable. The reason is that the ring body 1 can maintain sufficient elasticity without being permanently deformed even if it is used (mounted) for a long period of time, thereby maintaining excellent sealing performance (sealing performance). Then, when the shaft portion 12 is pulled out from the state shown in FIG. 9 (reversely) to the state shown in FIG. 7, even if the dimension is loose with respect to the shaft portion 12 as described above, the linear spring 4
Thus, the ring body 1 can be effectively prevented from falling off.

発的に密着できる。The present invention having the above-described structure has the following great effects. (According to claim 1) With a simple structure, it is possible to reliably prevent an accident (defective) in which the ring body 1 falls off the shaft portion 12. (According to claim 1) The entire C-ring is compact, and it is convenient because it can be used particularly with the dimensions of the hole 14 and the shaft portion 12 for the conventional C-ring. In other words, the linear spring 4 is added by effectively utilizing the internal space of the ring body 1 and can be mounted as it is in the conventional C ring mounting space portion (space saving). Since it can be prevented from falling off (according to claim 1), the work of mounting the shaft portion 12 in the hole 14 and the disassembling work (at the time of repair / inspection / replacement, etc.) (take-out work) are efficiently performed. Therefore, there is no need to worry about damaging the important parts for sealing, such as the sealing stepped portions 11a and 14a shown in FIG. In particular (according to claim 1), even when sealing the shaft portion 12 to be inserted into the deep portion of the deep hole 14, it is possible to reliably and smoothly perform the mounting work and the removal work of the C ring. it can. In addition, the degree of freedom in form when the C ring is incorporated is increased. Since the linear spring 4 has a simple shape (according to claim 2), it can be easily manufactured and can be easily assembled into the ring body 1. (According to the third aspect) It is possible to reliably and elastically adhere to the outer peripheral surface of the shaft portion 12.
