Anti-shedding mechanism (or anti-dropout component) (9,12) has gasket 9 and bushing 12.For example, gasket 9 is to be formed
For 3 millimeters of plate thickness of flat iron plate, as shown in figure 5, being formed with 12 millimeters of diameter of through hole 9a.In through hole 9a,
Top and bottom are formed with 45 degree of section of corner portion 9b, 9b.Have the insertion hole 12a's with 9 millimeters of diameter in through hole 9a engaging
The bushing 12 of natural rubber.
The ring-type that bushing 12 is 1.5 millimeters of plate thickness, outer diameter are 12 millimeters of diameter identical with through hole 9a.The spiral shell of bolt 10
Silk portion 10b is such as 10 millimeters of outer diameter.Then, bushing 12 is previously inserted in the through hole 9a of gasket 9.Therefore, by bolt 10
Screw 10b be inserted into the insertion hole 12a of above-mentioned bushing 12.Diameter due to the outer diameter of screw 10b than being inserted into hole 12a
Greatly, therefore, bolt 10 can prevent from loosening with anti-shedding mechanism (9,12).By bolt 10, inserted with the screw 10b of bolt 10
Anti-shedding mechanism (9,12) constitute sliding rail fastener T (referring to Fig. 4).
Anti-shedding mechanism (9,12) be not limited to it is as shown in Figure 5 only gasket 9 in addition to corner portion 9b, 9b with
The outer part through hole 9a has bushing 12.For example, it is also possible to be the composition illustrated below referring to Fig. 6~Fig. 8.
Fig. 6 indicates the 1st variation of anti-shedding mechanism (9,12).The anti-shedding mechanism (9,12) of 1st variation is mounted
Through hole 9a is covered on the thickness direction of gasket 9 for bushing 12 and a pair of of corner portion 9b is whole.In this case, bushing
12 is substantially the same with the thickness of gasket 9.Fig. 7 indicates the 2nd variation of anti-shedding mechanism (9,12).The anticreep of 2nd variation
It falls in mechanism (9,12), bushing 12 covers through hole 9a on the thickness direction of gasket 9, and only covers upper and lower corner portion 9b
Within (gasket) thickness direction central portion.In this case, the thickness of bushing 12 is thinner than the thickness of gasket 9.In Fig. 7 institute
In the example shown, bushing 12 is installed as covering respective a part of a pair of of corner portion 9b, 9b.
Bushing 12 is installed as not only enclose through hole 9a on the thickness direction of gasket 9 as a result, also encloses a pair of of corner portion
A part of at least one of 9b, 9b, mounting area increases as a result, and obtains the threaded engagement of thickness direction.Therefore, it serves as a contrast
The installation strength of the opposite gasket 9 of set 12 improves and becomes difficult to remove from gasket 9.Therefore, it is inserted by the screw 10b of bolt 10
When entering the insertion hole 12a of bushing 12, the worry that falls off almost without bushing 12 from gasket 9.
As noted above, the corner portion 9b being made of plane is equipped in the opening edge of through hole 9a.But for chamfering
Portion is not defined as the above-mentioned chamfering being made of plane, can also be the so-called R chamfering being made of curved surface.Fig. 8 shows anticreeps
Fall the 3rd variation of mechanism (9,12).In the example shown in Fig. 8, in the opening edge of through hole 9a, use what is be made of plane
The corner portion 9b and R corner portion 9c being made of curved surface, it is also possible to use a pair of R corner portion 9c, 9c in opening edge.3rd
The anti-shedding mechanism (9,12) of variation pass through be formed as on the thickness direction of gasket 9 cover R corner portion 9c a part or
Person is whole, to realize the raising of the installation strength of opposite gasket 9.It is not formed in post-processing in addition, R corner portion 9c can also be
And the angle of collapsing generated when to be stamped and formed out through hole 9a.In the case where forming R corner portion 9c with angle of collapsing, add after capable of reducing
The manufacturing cost of work amount.
In the chamfering that the opening edge of the insertion hole 12a of bushing 12 can also form R chamfering or be made of plane.In Fig. 8
In, the opening edge shown in insertion hole 12a forms section shape as the example of the portion the R 12b of circular arc.In addition, insertion hole 12a
Section shape does not limit.For example, the section shape of insertion hole 12a can also be arc-shaped.
Fig. 9 indicates the top view of the 4th variation of anti-shedding mechanism (9,12).4th variation anti-shedding mechanism (9,
12) outer shape of gasket 9 is set as rectangle.Figure 10 indicates the top view of the 5th variation of anti-shedding mechanism (9,12).5th
The outer shape of gasket 9 is set as round by the anti-shedding mechanism (9,12) of variation.In addition, gasket 9 is without that must have circle
Through hole 9a.For example, it is also possible to which the through hole of "U" shaped is arranged in gasket 9.In this case, bushing 12 can be held
It changes places inside from one side of opening of the "U" shaped of gasket 9 to "U" shaped and is inserted into.
In anti-shedding mechanism (9,12), required insertion force when being inserted into the screw 10b of bolt 10 to insertion hole 12a
Outer diameter depending on screw 10b.For example, the outer diameter of screw 10b is bigger, insertion force required for being inserted into becomes bigger.Separately
Outside, insertion force is determined by screw 10b with respect to the mesh degree of bushing 12.As shown in figure 11, the bushing of insertion force is determined
12 element in shape is radial distance Wa, thickness direction distance La and sectional area Sa in the cross-sectional shape of bushing 12
This three.Here, so-called thickness direction means the thickness direction of gasket 9.In addition, cross section is to cut with circumferential orthogonal face
Disconnected section.Here, the section shape of the insertion hole 12a of bushing 12 becomes arc-shaped.Sectional area Sa, which is equivalent to, grinds net with Hang
The part of line.In particular, radial distance Wa is in bushing 12, the position compared with the screw outer diameter reference dimension d of screw 10b
Maximum radial distance in the part for more leaning on path side (central side of insertion hole 12a).
Thickness direction distance La is to be located at the portion for more leaning on path side in bushing 12, compared with screw outer diameter reference dimension d
The maximum gauge direction distance divided.Sectional area Sa is located in bushing 12, compared with screw outer diameter reference dimension d more by path
The sectional area of the part of side.For these three elements, more increase the numerical value of each element, more increase with the mesh volume of screw 10b,
Therefore, it is capable of increasing the insertion force of screw 10b.
The deviation of certain degree is generated due to the deviation etc. between the batch of bolt 10 for the outer diameter of screw 10b.Therefore,
When bushing 12 to be set as circular and determine its cross-sectional shape, firstly, by the outside diameter tolerance for screw 10b most by shadow
Loud radial distance Wa is set between the screw outer diameter reference dimension d of screw 10 and screw effective diameter reference dimension d2 substantially
Intermediate value.Then, thickness direction distance La and sectional area Sa is set, to obtain desired insertion force.
The plan view shape that bushing 12 is not limited to insertion hole 12a is circular ring-type.Figure 12 expression anti-shedding mechanism (9,
12) the 6th variation.In the 6th variation, bushing 12 has distance from center to inner surface circumferentially continuous and periodically
The insertion hole 12c of increase and decrease.
Figure 13 indicates the 7th variation of anti-shedding mechanism (9,12).In the 7th variation, bushing 12 have from center to
The insertion hole 12d that the distance of inner surface increases and decreases periodically in circumferential two stages.For being inserted into hole 12c, 12d, the screw being inserted into
Portion 10b becomes smaller with the disturbance range of bushing 12 compared with complete cycle, therefore, the deviation of the outer diameter of opposite screw 10b, it is difficult to
It is affected and the variation of insertion force tails off.
Bushing 12 is not limited to the installation method of gasket 9.Can also be simple engaging, can also use bonding agent into
Row bonding.
Embodiment according to the present invention, the fixation guide rail 2 of sliding rail 1 is by being set to the through portion 2f of bottom wall 2e, by spiral shell
Bolt 10 is fastened with the nut 11 for being fixed on floor 13 and is fixed.The fixed mechanism that individual component is separated with sliding rail 1, energy are not needed
