As shown in the figure, the main body 1 is integrally connected to the left and right end caps 2 and 3 by two bolts 4, respectively. This bolt hole 5 fixed to a member, for example, in JP-A-54-91651, is provided in the flat portions on both sides of the raceway groove 6 of the main body, but considering the counterbore in which the head of the mounting bolt is embedded, the bolt hole 5 is provided in the flat portion on one side. The width A must be at least twice the diameter of the mounting bolt. In bearings with small load capacity, rolling elements 7
The diameter of the raceway groove 6 can be made small, and the groove width of the raceway groove 6 can also be made small, but the diameter of the mounting bolt cannot generally be made too small due to strength and workability. First, there was a drawback that the width of the bearing could not be reduced even though the load capacity was reduced.

したものである。 The purpose of this invention is to provide a small planar motion bearing that can handle a small load capacity.The purpose of this invention is to connect the main body and end cap without using bolts, and to connect the end cap to the end cap without providing mounting bolt holes in the main body. This makes it possible to reduce the width of the flat portions on both sides of the raceway groove of the main body, thereby achieving miniaturization of the bearing.

の脱落を案内する保持ワイヤである。 The embodiment of the present invention in which rod-shaped rollers are used as the rolling elements shown in FIGS. 3 and 4 will be described below. The main body 11 has two upper and lower rectangular grooves formed in the axial direction and parallel to each other. a raceway groove, and a thin axial concave groove 18 parallel to the bottom surface of the raceway groove on the outer surface of both sides,
Four holes 21 are provided on each end surface, two on each end surface, for alignment with the end caps 12 and 13. 2 end caps 12,1
3 is formed with semicircular grooves interconnecting each of the raceway grooves of the main body 11 and a recess into which the return guide 16 having a semicircular cross section is fitted, and on the outer side surfaces and outer end surfaces of both sides. , grooves 19 that can be continuous with the grooves 18 of the main body are provided, respectively. Also,
The end cap is provided with a bolt hole 20 in the center thereof that passes through the main body 11 in the vertical direction, and a counterbore is provided on the top surface in which the head of the mounting bolt is embedded, and the mounting bolt hole 20 is formed in the semicircular arc groove. One location is provided where it will not interfere with the Furthermore, the inner end surfaces of the end caps 12 and 13 are each provided with two protrusions (not shown) that fit into the four holes 21 of the main body. Main body 11 and 2

提供できる効果がある。 The planar motion bearing of the present invention constructed as described above has no mounting bolt holes in the flat portions on both sides in the width direction of the raceway groove in which the rolling elements circulate and roll, and also has no mounting bolt holes for fixing the end cap to the main body. Since there is no screw hole, the width dimension of this part of the main body (width dimension A in FIG. 1) can be made small. Therefore, it is possible to miniaturize a bearing with a small load capacity, and it is possible to provide a bearing for planar motion with a small size that can be applied to light and small sliding members.
