Thereafter, it is scooped up by the turning path 9, guided to one end of the return path 8, and guided through the return path 8 to the other end of the return path 8. Then, it is again guided to the load rolling path 7 via the direction changing path 9. By repeating this, the rolling elements 3 # 3 circulate in the infinite circulation path 10 with the movement of the movable body 4.

On the other hand, end plates 22 and 22 shown in FIGS. 5 and 6 are attached to the outer surfaces of the lid members 21 and 21, respectively. The end plate 22 is also substantially gate-shaped, and is attached to the lid member 21 by screwing screws 24 ‥ 24. A seal member S <b> 3 extending in a direction orthogonal to the moving direction of the movable body 4 is provided on a peripheral edge of the inner portion 221 of the end plate 22 facing the track 2.
The tip of the seal member S3 is provided such that the lip portions 12a and 12b arranged in a V-shaped cross section are arranged side by side in the moving direction of the movable body. Lip part 1 arranged outside
Reference numeral 2a functions as a scraper that pushes foreign substances attached to the surface of the way 2.

FIG. 7 shows a cross section in a direction perpendicular to the moving direction of the movable body 4 of the rolling guide device 1 (the direction penetrating the plane of FIG. 7), and shows a half-side enlarged view.
The two load rolling paths 7, 7 shown in this figure are sealed on both sides of the center line CL side and the lower side. On the center line CL side, the seal is sealed by a seal member S1 extending in the moving direction of the movable body 4 (the direction penetrating the plane of FIG. 7). The seal member S1 is provided on an inner plate P disposed at a position of a surface 32 facing the upper surface of the track base 2 of the movable body 4.

On the other hand, the lower side is sealed by a seal member S2 extending in the moving direction of the movable body 4 (the direction penetrating the paper surface of FIG. 7). The seal member S2 is attached to a side plate P2 disposed at a position on the lower surface 33 of the movable body 4. Similarly, the seal member S2 has two lip portions 12a and 12b arranged at the tip thereof in a V-shaped cross section,
The tip of the track base 2 is in contact with the slope of the side recess.

In addition, the rolling elements 3 ‥ 3
Grease G is filled as a lubricant in order to prevent smooth rolling and seizure. The sealing members S1 and S2
It not only prevents foreign matter from entering the infinite circulation path 10, but also prevents the filled grease G from leaking outside. The grease G is filled from the filling port 25 of the end plate 22 (see FIG. 1), and the lid material 2 is communicated through the communication port 26 of the lid material 21 communicating with the filling port 25.
It is guided to a grease guide path 27 provided inside 1. The grease guide path 27 communicates with the direction change path 9 which forms a part of the endless circulation path 10, and the grease G
Is introduced into the direction change path 9 and charged into the endless circulation path 10 (see FIG. 4).

In the present embodiment, the longitudinal ends of the side plate P1 and the seal members S1 and S2 of the inner plate P2 are abutted from the side of the seal member S3 of the end plate 22. In the portion of the load rolling path 7, the moving direction of the movable body and the seal member S which is formed in a double lip are both orthogonal to the moving direction.
All gaps are closed. Therefore, it is possible to dramatically improve the dustproof effect and effectively prevent the grease G from leaking out (see FIG. 8).

Further, in the present embodiment, the sealing members S1, S
Grease G is also sealed between the two lip portions 12a and 12b. If the number of the lip portions 12 is increased, the contact length with the way 2 is increased accordingly, and the contact resistance is increased, and the sealing effect itself can be improved.
The smooth movement of the movable body was sacrificed. On the other hand, even if a plurality of lips 12a and 12b are provided in the seal members S1 and S2 extending in the moving direction of the movable body, the sealing effect itself can be improved, but foreign substances adhering to the surface of the way 2 can be improved. The effect of displacing can not be expected so much. Therefore, as in the present embodiment, the grease G is applied to the lip portions 12a,
Grease G plays a role as a lubricant by being enclosed between 12b, and a smooth movement of the movable body can be secured.

Next, referring to FIGS. 9 to 17, each of the seal members S1, S2, each of the plates P1, P2 provided with the seal members S1, S2, and each of the plates P1, P2
The details of the state of attachment will be described.

FIGS. 9 to 13 show the inner plate P1 provided with the seal member S1 and a method of attaching the inner plate P1. As described above, the inner plate P1 is disposed at the position of the downward facing surface 32 facing the upper surface of the track base 2 of the movable body 20 of the movable body 4 (see FIG. 7).
It is attached to both ends by locking both ends in the longitudinal direction (left-right direction in FIG. 9).

As shown in FIGS. 9 and 10, the inner plate P1 has a substantially trapezoidal cross section.
4 is provided with a seal member S1 formed of a rubber material or the like at both ends in the width direction (vertical direction in FIG. 9). Substrate part 14
On the back surface of the top surface, a convex portion 14a is provided over the entire length.

A plate holding portion 211 is provided on a surface of the cover 21 facing the movable body 20. The plate holding portion 211 is provided with an engagement groove 212 having substantially the same shape as the cross-sectional shape of the substrate portion 14, and two projections 213 and 213 are provided below the engagement groove 212. Inner plate P
1 is locked by inserting the longitudinal end of the substrate portion 14 into the engagement groove 212 of the plate holding portion 211. At this time, the convex portion 14a of the substrate portion 14 is sandwiched between the two convex portions 213 and 213 of the plate holding portion 211. Therefore, the inner plate P1 can be easily and reliably fixed without using any fixing means such as screws.

On the other hand, the length of the sealing member S1 is longer than the length of the substrate portion 14 so that the end of the sealing member S1 can abut against the side of the sealing member S3 provided on the end plate 22. Have been.

The sealing members S1 and S1 are fixed with their ends abutting against the lip portion 12 inside the sealing member S3 from the side. Therefore, no gap is formed at the ends of the seal members S1 and S1. For this reason, it is possible to prevent external leakage of the grease G,
For example, the sealing member S provided on the end plate 22
Even if the foreign material 3 cannot prevent the foreign matter adhering to the surface of the way 2, the foreign material does not enter the infinite circulation path 10.

The lower half of the seal member S1 is provided with lip portions 12 having a V-shaped cross section.
However, the number of the lip portions 12 is not limited to two and does not prevent providing three or more lip portions.

In this embodiment, as shown in FIG. 11, the tip of the lip 12 has a substantially circular cross section. If the tip of the lip 12 is formed at an acute angle, the following problem occurs.

That is, although there is a line contact with the way 2, the place where the pressing pressure of the seal member S1 against the way 2 may slightly change due to a manufacturing error or the like. If the pressing pressure is increased, the lip portion 12 is deformed, so that line contact cannot be maintained and surface contact occurs. For this reason, frictional resistance increases, and smooth movement of the movable body 4 is hindered.

However, as in the present embodiment, if the tip is formed so that its cross-sectional shape is substantially circular, even if the lip 12 is deformed, the lip 12
By simply shifting the contact position, the line contact can always be maintained, and the smooth movement of the movable body 4 is not hindered.

Further, of the two lip portions 12a and 12b provided on the seal member S1, the pressing pressure of the lip portion 12b closer to the load rolling path 7 is reduced by the lip portion 12a located farther from the load rolling path 7. May be provided to be smaller than the pressing pressure.

In this case, as a method of providing a difference in the pressing pressure of the lip portion, for example, the length of the lip portion 12a is formed longer than the length of the lip portion 12b, and the lip portions 12a and 12b are provided with an interference. Mold the same length,
It is preferable to provide a difference in the pressing pressure by, for example, attaching the seal portion S1 by inclining to the load rolling path 7 side.

FIGS. 14 to 17 show a side plate P2 provided with a seal member S2 for sealing the lower side of the load rolling path 7, and a method of attaching the side plate P2.

The side plate P2 has a flat plate portion 15a.
The substrate portion 15 includes an inclined portion 15b that forms an obtuse angle with the flat plate portion 15a, and a seal member S2 attached to the inclined portion 15b.

An arc-shaped engagement groove 15c is formed in the flat plate portion 15a of the substrate portion 15 over the entire length. The engagement groove 15c is provided at a predetermined distance from the end face in the width direction of the flat plate portion 15a. In addition, a notch 15d is provided at a corner between both ends in the longitudinal direction and an end in the width direction.

The side plate P2 is attached to the lid 21 while being locked thereto. The cover member 21 has a cut portion 28 near the lower end thereof, which is formed over a surface facing the movable body 30 and a surface facing the track base 2. The side plate P2 is attached to the cut portion 28 by fitting both ends in the longitudinal direction.
Further, the end portion in the longitudinal direction (the left-right direction in FIG. 14) is attached to the end plate 22 by abutting against the side of the seal member S3.

On the surface of the cut portion 28 facing the engagement groove 15a, a projection 29 engaging with the engagement groove 15c of the substrate portion 15 is provided.
Is provided. The protrusion 29 is engaged with the engagement groove 15c to prevent the side plate P2 from falling out in the width direction of the movable body 4.

The width of the cut portion 28 in the vertical direction is
At the location 9, the distance from the tip of the projection 29 to the surface facing the projection is formed slightly smaller than the thickness of the side plate P2. For this reason, in order to engage the engaging groove 15c with the projection 29, it is necessary to push up the notch 28 vertically when inserting the side plate P2. However, the rigidity is not so high in the vicinity of the entrance of the cut portion 28, so that it can be easily pushed out.
When inserting 2, it becomes difficult to push and spread the notch 28. To solve this inconvenience, the side plate P2
Notches 15d are provided at both ends in the longitudinal direction, and are shaped so that the side plate P2 can be easily fitted.

The sealing member S2 of the side plate P2
Also, the section on the side in contact with the way 2 has a cross-sectional shape of V
The lip portions 12a and 12b have a character shape. Note that the number of the lip portions 12 is not limited to two, and three or more lip portions may be provided. Further, also in the present sealing member S2, the tip shape of the lip portion 12 has a substantially circular cross section.

Further, with respect to the seal member S2, the interference of the lip 12b on the side closer to the load rolling path 7 may be smaller than the interference of the lip 12a located farther from the load rolling path 7.
