As shown in Utility Model Publication No. 48-5808, in conventional casters with wheel guards, the wheel guard was fixed integrally with the axle and could not slide in the axle direction. That is, in the conventional configuration, a wheel is fitted onto an axle via a pair of left and right bearings, the wheel is covered from the outside with a wheel guard, and a pair of left and right collars, etc. are interposed between the wheel guard and each of the bearings. The structure is such that each of the above-mentioned bearings is sandwiched and fixed between these collars. However, with this structure, when installed on the support yoke, the collar is fixed between the fixed side of the bearing and the wheel guard, which is the non-rotating part of the wheel, so the collar may become eccentric during assembly or the support yoke may The problem is that when the wheel guard collides with the wheel guard in a twisted state and is tightened, the wheel becomes difficult to rotate.As a result, it takes time and effort to assemble the entire caster for adjustment, making the work extremely troublesome. It was hot. In addition, when this type of caster is used in a textile factory, for example, thread waste scattered on the floor gets entangled with the axle, but as mentioned above, the wheel is held in the axial direction by the collars on both sides via the bearing, so that it remains constant. Another problem was that if the thread was held in place, it would be very troublesome to remove the lint that had become entangled with the axle. In addition, in the swivel wheel of Utility Model Publication No. 47-21797, in order to enable the wheel to move up and down with respect to the axle, a V
A configuration is disclosed in which a slider having a letter-shaped inclined surface is attached, a spring fitted externally on an axle is pressed into contact with the slider, and the slider is displaced in the expansion/contraction direction along the inclined surface by the force applied to the wheel. has been done. However, in the above configuration, it is necessary to provide two springs in order to displace the slider in the direction of separation or approach, but if two springs are provided on the outside of the wheel along the axle, the wheel will easily swing. The disadvantage is that walking is not stable.

In order to solve the above problems, this invention includes a wheel that is rotatably fitted onto an axle shaft supported by a support yoke via a pair of left and right bearings, and a pair of left and right wheel guards that cover the wheels from the outside. In a caster with a wheel guard, (a) a pair of left and right bearings are provided, which are held at intervals on both sides of the bearing hole of the wheel and are installed along the axle; (b) a pair of left and right bearings are provided that are mounted along the axle on the outside of the bearings; (c) a pair of left and right wheel guards fitted externally, one of which is slidable relative to the axle, and which is compressibly interposed between the slidable wheel guard and a bearing near the wheel guard; (d) a collar interposed between the other wheel guard and the nearest bearing to keep them spaced apart and fitted externally to the axle; It is.

Thereby, the wheel is elastically supported by the wheel guard spring on one bearing side on the axle. For this reason, unlike the case where the wheel is sandwiched between the left and right collars from both sides and fixed in a predetermined position in the axial direction, the entire caster can be assembled easily, and the frequency of eccentricity of the collar during assembly is greatly reduced. High rotational accuracy can be obtained. In addition, as mentioned above, by elastically supporting one side of the wheel, when thread waste etc. becomes tangled around the axle, the axle or wheel can be moved in the axial direction. Thread waste etc. can be easily removed.

An embodiment of this invention will be described below based on the drawings. The illustrated wheel 1 is composed of a wheel 10 and a tie 11, and the wheel 10 has a bearing cylinder portion 1 that branches into two toward the shaft center and extends outward in the axial direction.
It has 0a and 10b. A pair of left and right bearings 2, 3 are attached to these bearing cylinder parts 10a, 10b in a bearing case 20,
It is fitted through 30. At this time of fitting, a spacer 4 is interposed between the bearings 2 and 3 to hold them at a predetermined distance. Each bearing case 20, 30 has outward locking jaws 20a, 30a for engaging with the outer ends of the bearing cylinder portions 10a, 10b, and these outward locking jaws 2.
It has annular bulging side wall portions 20b, 30b that bulge outward in the axial direction from 0a, 30a. Each of the bearings 2 and 3 is fitted onto an axle 5 for rotatably supporting the wheel 1 on a support yoke 8, and a pair of left and right wheel guards 6, 7 are provided on the axle 5 to cover the wheel 1 from both sides. is slidably inserted. The axle 5 of this embodiment consists of an axle 50 made of a bolt with a head, and a nut 53 screwed onto the tip of the axle 50 via a washer 52. The axle 50 includes a coil-shaped wheel guard spring 100 interposed between one bearing 2 and the wheel guard 6, and a collar 101 interposed between the other bearing 3 and the wheel guard 7. It is inserted. An outer jaw portion 102 is integrally formed at the inner end of the collar 101, and this outer jaw portion 102 is movably inserted into and engaged with the inside of the bulging side wall portion 30b of the bearing 3. Next, the assembly of the above embodiment will be explained.
First, the bearing cylinder portions 10a, 10 of the wheel 10 are prepared in advance.
The bearings 2 and 3 are fitted to b with a spacer 4 interposed between them, and the bearing case 20,
30 outward locking jaws 20a, 30a are kept engaged. Further, a collar 1 is provided in the gap between one of the bearings 3 and the bulging side wall portion 30b of the bearing case 30.
The outer jaw portion 102 of 01 is interposed and engaged in advance. In this state, as shown in FIG. 3, from the shaft hole of one support yoke 8, the wheel guard 6, the wheel guard spring 100, the bearing 2, the spacer 4, the other bearing 3, the collar 101,
Axle 5 in the direction of passing through the wheel guard one after another
0 is press-fitted through the axle 50, and the nut 53 is screwed onto the distal end side of the axle 50 via the washer 52, thereby completing the assembly. The caster assembled in this way is attached to the other wheel guard 6 by the wheel guard spring 100.
is attached to the support yoke 8 movably (elastically in the axial direction)
It is installed and ready for use. As a result, the wheels held between the support yokes 8, 8 can be adjusted autonomously by expanding and contracting the wheel guard spring 100 even if the mounting surfaces of the collar and the wheel guard and the wheel guard and the support yoke do not align uniformly. It becomes possible to do so. Furthermore, when the wheel guard 6 is moved in the axial direction when thread waste or the like becomes entangled with the axle shaft 5 during use, the entangled thread waste or the like can be easily removed. In addition, the caster in which the wheel 1 is elastically supported in the axial direction as described above,
Unlike the case where the wheel 1 is held at a fixed position in the axial direction on the axle 5 by sandwiching the wheel 1 between collars from both sides,
Assembly is extremely simple, and smooth rotational accuracy can always be achieved.
