ーブル12の移動に伴って転動するようにしている。The linear roller guide bearing 1 is used by being interposed between a track base 11 extending in the axial direction and a movable table 12 which is a long block body having a substantially U-shaped cross section and arranged so as to straddle the track base 11. To be The trackway 11 has a rolling surface 13 for load rollers, which is a vertically inclined surface at the tip of the left and right jetty that protrudes in the horizontal direction.
On the other hand, the movable table 12 has an axial V-shaped groove 14 on the inner side surfaces of both sleeve portions and a bolt insertion hole 15 penetrating from the depth of the V-shaped groove 14 to the outer side surface of the sleeve portion. There is. The outer inclined surfaces 1c and 1d of the linear roller guide bearing 1 are fitted into the respective V-shaped grooves 14 of the movable table 12, and the bolts 16 inserted into the bolt insertion holes 125 are screwed into the mounting screw holes 9. The linear roller guide bearing 1 is attached to the movable table 12. Load roller B1
Is in contact with each rolling surface 13 for the load rollers of the track base 11 and rolls as the movable table 12 moves.
従来の直線ローラ案内軸受１にあっては、円筒ローラ

けたローラ保持器８で循環移動可能に保持されるにすぎ
ないから、直線ローラ案内軸受１を軌道台11から取り外
したとき、負荷ローラB1が直線ローラ案内軸受１から脱
落するおそれがある。In the conventional linear roller guide bearing 1, the cylindrical roller 7 is rotatably held by the roller retainer 8 attached to the bearing body 6 with a small gap between the end faces thereof. When the roller guide bearing 1 is removed from the way 11, the load roller B1 may fall off the linear roller guide bearing 1.
そこで、該ローラの脱落を防止し、直線ローラ案内軸
受１の組立を容易にするために、軸受本体６の内側凹所
に図示しない断面ほぼＵ字形で軸方向に延びる脱落防止
用の取付体を取付けて、負荷ローラB1の内周を転動自在
に保持することが提案されている。Therefore, in order to prevent the rollers from falling off and to facilitate the assembly of the linear roller guide bearing 1, an inside of the bearing body 6 is provided with a mounting body for preventing falling that extends in the axial direction and has a substantially U-shaped cross section. It has been proposed to mount and hold the inner circumference of the load roller B1 in a rollable manner.
しかし、その脱落防止用の取付体は断面ほぼＵ字形の
長尺体であるから、製作が面倒で金型代が高価であり、
しかも製作誤差や取付誤差により負荷ローラB1の転動を
妨げ易いという問題点がある。However, since the attachment preventing body is a long body having a substantially U-shaped cross section, it is troublesome to manufacture and the die cost is expensive.
In addition, there is a problem that the rolling of the load roller B1 is likely to be hindered due to manufacturing errors and mounting errors.
また、従来の直線ローラ案内軸受１にあっては、取付

も合わないと容易にガタが生じてしまい易いという問題
点もある。Further, in the conventional linear roller guide bearing 1, the screw holes 9 for the mounting bolts are formed on the outer inclined surfaces 1c, 1d of the bearing body 6.
Since they are provided in the diagonal direction in the main body from the ridges intersecting with each other, there is a problem that drilling work and tapping work of the bolt screw holes 9 are extremely difficult to perform. In addition, since the bolts 16 are attached from only one direction, there is a problem that if the attachment angle does not match even a little, backlash easily occurs.

A pair of roller passages and a partition wall are formed by notching the outer ridge portion and the inner ridge portion in a stepwise manner at both ends of the character shape that extend in the axial direction, and the rollers inside and outside the partition wall are formed. A bearing main body in which one of the passages serves as a load roller passage; an end cap fixed to both ends of the bearing main body in the axial direction and provided with curved passages that communicate the pair of roller passages; A large number of cylindrical rollers which are rotatably inserted into an elliptical infinite circulation path consisting of curved paths and whose ridges have inclined surfaces, and cylinders which cover the outer end surface of the cylindrical rollers and at least are inside the partition wall. A first roller retainer fixed to at least an outer surface of a partition wall of the bearing main body, the first roller retainer having a drop-preventing protruding edge portion adjacent to one inclined surface of the roller on a side edge extending in the axial direction; Close the bearing body A second roller retainer which is fixed to a plane formed between the roller passages and has an axially long rectangular cross section whose side edge extending in the axial direction is close to the other inclined surface of the inner cylindrical roller. The bearing main body has a plurality of bolt insertion holes that extend from the outer surface of the partition wall formed between the roller passages to the outer surface on the opposite side, and are alternately arranged along the axial direction in a direction intersecting with each other. And at least one of the outer surface of the bearing body facing the outer surface of the partition wall and the outer surface of the partition wall overhangs to the outside of the first roller retainer at an intersecting angle, and the load side The mounting surface corresponding to the inner roller passage or the outer roller passage is formed.
