 1 to 3 show an embodiment of the present invention.

This is an example of a hanging door, and a hanging door 6 is hung on the upper rail 2 via a runner 4 and is movably provided.
The runner 4 includes a support member 10 that is embedded and fixed in an embedding hole 8 at an upper end portion of the hanging door 6, and a runner member 12 that runs in the rail 2.
And a screw shaft 14 connecting the support member 10 and the runner member 12. The runner member 12 is composed of a mounting body 16 formed integrally with the screw shaft 14 and located inside the rail 2, and wheels 18, 18 provided on both sides of the mounting body 16. Further, the mounting body 16 is formed with a shaft hole 19 for mounting the wheels 18, 18.

The support member 10 is roughly composed of a support main body 22 that is directly fixed to the embedding hole 8 with fixing screws 20 and 20, and an accommodating portion 24 that is accommodated and fixed in the support main body 22. In consideration of mounting strength, weight, manufacturing cost, and the like, for example, the support main body 22 may be formed of synthetic resin, and the accommodating portion 24 may be formed of metal. The accommodating portion 24 has a screw hole 24a into which the screw shaft 14 is screwed, and is integrally fixed to the supporting body portion 22 with a mounting screw 28 via a nut member 26 provided in the inner portion of the supporting body portion 22. It has become. Screw hole 24 in the housing 24
The hanging door 6 is vertically adjusted by adjusting the screwing amount of the screw shaft 14 with respect to a. In addition, in the mounting screw 28, reference numerals 30 and 32 represent a flat washer and a spring washer, respectively.

The wheel 18 is composed of a wheel body 34 and a shaft portion 36 integrally formed on the inside of the wheel body 34. An insertion hole 38 is communicated with the wheel body 34 and the shaft portion 36, and the insertion hole 38
The axle pin 40 is inserted through the wheel 18, and the wheels 18, 18 are integrally assembled to the mounting body 16.

The wheel body 34 and the shaft portion 36 are, for example, the outer ring 42 and the outer ring.
An inner ring 44 that is inserted into the outer ring 42 from the outside, a plurality of spherical bodies 46 that are provided in the circumferential direction between the outer ring 42 and the inner ring 44, and the outer ring 42, the inner ring 44, and the inner ring 36 that are fitted into the inner ring 36 from the inner side of the outer ring 42. Can be configured to include a spherical body 46 and a stopper shaft 48 integrally assembled and held as a bearing structure.

Hereinafter, the configuration of the wheel 18 will be described in detail. A locking edge 42a for locking the sphere 46 is formed inside the outer ring 42 in the circumferential direction. The inner ring 44 has a cylindrical portion 44a that is inserted into a large diameter insertion hole 42b of the outer ring 42 and a small diameter insertion hole 42c that communicates with the insertion hole 42b.
And a collar portion 44b housed in the insertion hole 42b. A curved concave portion 44c that forms a space for accommodating the spherical body 46 with the insertion hole 42b of the outer ring 42 is formed inside the flange portion 44b over the entire circumference. The inner hole of the inner ring 44 serves as an insertion hole 38 into which the shaft pin 40 is inserted.

The stop shaft 48 can be composed of a cylinder body 48a that is closely fitted and inserted into the cylinder portion 44a of the inner ring 44, and a flange portion 48b that is formed outward on the outer surface of the cylinder body 48a. Therefore, in this example, the shaft portion 36
Has a laminated structure of a cylinder body 48a of the stop shaft 48 and a cylinder portion 44a of the inner ring 44. The flange portion 48b restricts the rattling of the outer ring 42 in the axial direction. Further, the inner ring 44 is formed with a contact surface 44d that contacts the outer end of the cylinder body 48a, and the inner ring 44 is positioned with respect to the outer ring 42 by the contact.

As an example of the process of assembling the wheel 18, first, the stop shaft 48 is fitted to the outer ring 42 from the inner side. The outer side 48c of the cylinder main body 48a of the stop shaft 48 has a length protruding from the locking edge 42a of the outer ring 42, whereby an annular temporary accommodation space in which the spherical body 46 does not fall down is formed. After arranging a plurality of spheres 46 in this temporary accommodation space, the inner ring 44 is inserted from the outer side of the outer ring 42. The inner ring 44 is closely fitted to the stop shaft 48, and the outer ring 42 is prevented from coming off by the flange portion 48b of the stop shaft 48.
2. A bearing structure in which the inner ring 44, the sphere 46 and the retaining ring 48 are integrally assembled can be obtained.

The wheel 18 assembled together has its shaft portion 36 attached to the mounting body
It is inserted into 16 shaft holes 19 and temporarily fixed. The shaft portion 36 can obtain a stable holding state of the wheel 18 with respect to the mounting body 16 only by an insertion operation into the mounting body 16, and the insertion amount with respect to the mounting body 16 is effectively restricted by the collar portion 48b of the stop shaft 48. It is desirable to form the length.

After the wheels 18, 18 are temporarily fixed to both sides of the mounting body 16, the shaft pin 40 is inserted from both sides through the insertion hole 38 across both sides. The shaft pin 40 has a retaining portion 40a at the rear end and a hollow portion 40b at the front end, and after being inserted, the hollow portion 40b is expanded by a tool such as a punch and caulked so as to be secure. As a result, the wheels 18, 18 are integrally assembled with the mounting body 16.

In addition, in this example, an example of application to a hanging door and an upper runner is shown, but the present invention is not limited to this, and can be applied to a sliding door or the like and can be applied to upper and lower runners.

Next, FIG. 4 shows another embodiment of the present invention, particularly a modification of the inner ring 44 and the stop shaft 48. The inner ring 52 is composed of a long tubular portion 52a and a collar portion 52b that does not have a curved concave portion that directly contacts the spherical body 46. Further, the stop shaft 54 is composed of a cylinder body 54a only on the outer side and a collar portion 54b. Further, at the inner end of the outer ring 42, a housing recess 42d for housing the collar portion 54b of the stop shaft 54.
Are formed. In this example, the shaft portion 56 is the tubular portion of the inner ring 52.
It consists of 52a.

In each of the above-mentioned examples, the shaft pin 40 and the spherical body 46 are all made of synthetic resin. Therefore, no metallic noise is generated during traveling, smooth traveling can be obtained, and manufacturing cost can be reduced. In addition, it is less likely to rust and has a longer service life than those that use existing metal bearings.

As described above, if the shaft is inserted into the mounting body, the wheels are temporarily fixed, and the wheels are assembled integrally with the shaft pins, the wheels can be integrally assembled to the mounting body without being affected by the mounting accuracy. This can be done easily, so that the assembling work can be simplified and speeded up.
