おいて充分対応させることが可能となる。Since the present invention is constructed as described above, its most significant feature is that both the spline bearing and the spline bearing for linear guide are formed of the shaft (1) having a perfect circular cross section. It is not a shaft with a roughly diamond-shaped cross section or a complicated irregular cross-section such as a rice ball shape, so it is a simple rod material with a perfectly circular cross section that has been used for a long time and is indispensable for various machines. In addition, this makes it easy to process the ball transfer groove (2), and together with the mass production effect, it can be manufactured at low cost (13). Since the shaft member (a) has a perfect circular cross-section, it has a 1t/I structure and is easy to manufacture.
The method of using a guide as a guide is completely revolutionary and can significantly reduce the cost of spline bearings and spline bearings for linear guides, thereby eliminating the economic constraints mentioned above and making it easier to use The shaft circumference can be expanded, and since it has a line-contact sliding structure using balls, smooth sliding can be expected, eliminating problems such as horizontal accuracy and center roll. This makes it possible to fully respond to the situation.

換組付けでき、互換性もあるという便利も庄じる。In addition, since the guide shaft member (a) has a perfectly circular cross section, it is compatible, especially since there is no need to replace the linear guide purpose member (14) or the guide member Qllll as in the past, and it can be easily replaced and assembled. There is also the convenience of having one.

容易にできる。In addition, it can be used as a guide by simply drilling holes in the so-called linear guide purpose member of the main body.
Furthermore, since the kite shaft member (a) is in the shape of a round bar, it is possible to easily guide the linearly guided member in a tilted state.

を向上することができる。In addition, since the active pole array portions (5) are arranged in a facing state, they can sufficiently withstand charging in all four directions. Since the component force is directed toward the axis, so-called core loops can be prevented as much as possible, thereby further improving the precision of linear guidance.

By resin molding, it is possible to provide a spline bearing and a spline bearing for linear guides at even lower cost.
以上、所期の目的を充分達成することができる。As described above, the intended purpose can be fully achieved.
