Outer ring 33 is installed as by metal ball BA can be in the periphery rotation of inner ring 32.Between inner ring 32 and outer ring 33, seal member 34 is installed, prevents that foreign matter is blended between inner ring 32 and the outer ring 33, and the sliding agent that prevents from being coated between inner ring 32 and the outer ring 33 leaks.As shown in Figure 5, axial (the center of rotation axis direction) central portion on the outer peripheral face of outer ring 33,33 periphery is formed with slot part 33a along the outer ring.In the section of as shown in Figure 4 the center of rotation axis CA that comprises supporting roller 30,33 convex ground, the radial direction outside is crooked towards the outer ring for bottom 33a1 and the axially parallel of slot part 33a, the side wall portion 33a2 of slot part 33a.
As shown in Figure 7, the outer peripheral face at the outer peripheral face of the 2nd skin zone 36 outside the 1st of outer skin zone 37 and the axial both ends of outer ring 33 forms annularly, cover the 1st outer skin zone 36 and outer ring 33 around.Namely, it is side-prominent and at upwardly extending protuberance 37a of week that the axial central portion of inner peripheral surface one side of skin zone 37 is formed with outside the 1st skin zone 36 1 outside the 2nd, the slot part 36e of protuberance 37a and the 1st outer skin zone 36 is chimeric, and chimeric with the slot part 33a of outer ring 33 by the 1st outer skin zone 36.That is, the front end of protuberance 37a constitutes by the 1st outer skin zone 36 and enters in the slot part 33a.
Outside the 2nd on the axial both ends of skin zone 37, be formed with towards the outer ring 33 1 side-prominent protuberance 37b, 37b.The outer peripheral face butt at the axial both ends of protuberance 37b, 37b and outer ring 33.Thus, the axial end of outer board 36c, the 36c of the 1st outer skin zone 36 is highlighted the 37b of portion, 37b covering.The 1st outer skin zone 36 covers its periphery by the 2nd outer skin zone 37.And the axial central portion of the outer peripheral face of the 2nd outer skin zone 37 is crooked slightly, makes it compare axial two-end part in the radial direction outside.
As mentioned above, crust 35 is made of the 1st outer skin zone 36 and the 2nd outer skin zone 37 that covers the periphery of the 1st outer skin zone 36.Therefore, follow the on-off action of sliding door 13, supporting roller 30 rolls at guide rail 12, because this rolling outer peripheral face effect of skin zone 37 outside the 2nd has the load on the radial direction, therefore the 2nd outer skin zone 37 a little distortion are followed in this also a little distortion of skin zone 36 outside the 1st.Because the 1st outer skin zone 36 is made by impact absorbency better elastic material, therefore can when rolling, fully absorb the impact that is subjected to from rolling surface.Thus, can suppress vibration, the vibration of sliding door 13 and the generation of these rattles of supporting roller 30 self.And the 2nd outer skin zone 37 is that the nylon better than the durability of the 1st outer skin zone 36 hard is made, therefore, can protect the 1st outer skin zone 36.Therefore, when can guarantee durability such as withstand load, creep properties, abrasion performance according to the supporting roller 30 of present embodiment, the quietness in the time of can improving the on-off action of sliding door 13.
And, as mentioned above, because the portion that the draws in bending of guide rail 12, when roller assembly 20 moves along the portion of drawing in of guide rail 12, be assembled in that effect has axial load on the outer peripheral face of supporting roller 30 of horizontal supporting axle 22.Like this, on the outer peripheral face of supporting roller 30, even if effect has an axial load, because protuberance 37a is with slot part 36e is chimeric and the both ends of the surface butt of the protuberance 37b of the 2nd outer skin zone 37 and the 1st outer skin zone 36, so can prevent that the 2nd outer skin zone 37 from misplacing in the axial direction with respect to the 1st outer skin zone 36.
And, under the full-gear and full-shut position of sliding door 13, also have sliding door 13 situation different with respect to the angle of inclination of vehicle body when observing from the wheel fore-and-aft direction that constitute.Under this situation, vertical support axle 23,23 axis tilt with respect to longitudinal wall part 12a and longitudinal wall part 12c, in the outer peripheral face effect that is assembled in vertical support axle 23,23 supporting roller 30 axial load are arranged.Yet, because protuberance 37a is also chimeric with slot part 36e in this case, therefore can prevent that the 2nd outer skin zone 37 from misplacing in the axial direction with respect to the 1st outer skin zone 36.
And the axial central portion of 33 outer peripheral face is provided with at upwardly extending slot part 33a of week in the outer ring, and the axial central portion of the inner peripheral surface of skin zone 36 is provided with at upwardly extending protuberance 36d of week outside the 1st.And protuberance 36d and slot part 33a are chimeric.And the axial central portion of the outer peripheral face of skin zone 36 is provided with the slot part 36e that extends along circumferentially outside the 1st, and the axial central portion of the inner peripheral surface of skin zone 37 is provided with the protuberance 37d that extends along circumferentially outside the 2nd.And protuberance 37d and slot part 36e are chimeric.And protuberance 37a is chimeric with slot part 33a by the 1st outer skin zone 36.That is, outside the described the 2nd, be arranged in the most inboard part of radial direction (protuberance 37a) the inner peripheral surface of skin zone 37 and constitute to the distance on the radial direction of center of rotation axis CA that to be positioned at the distance of the outermost part of radial direction (the axial two end portions of outer ring 33) to the radial direction of center of rotation axis CA than the outer peripheral face from outer ring 33 short.
Under the situation that as above constitutes supporting roller 30, the 2nd outer skin zone 37 is overlapping to the orthography on described plane at least a portion and the outer ring 33 of the orthography on plane perpendicular to axial direction.Thus, mobile in the axial direction with respect to outer ring 33 even if the 2nd outer skin zone 37 wants, protuberance 37a can interfere with the side wall portion 33a2 of outer ring 33, therefore limits relatively moving of the 2nd outer skin zone 37.So, skin zone's 36 distortion outside the 1st can prevent that also the 2nd outer skin zone 37 is in the axially big dislocation of generation even if having axial load to make in the outer peripheral face effect of supporting roller 30.
And, the protuberance 37b of the 2nd outer skin zone 37 that is made of the material than the 1st outer skin zone 36 hard constitutes the axial both ends butt with outer ring 33, therefore, the load of sliding door 13 mainly acts on the supporting roller 30 that is assembled in horizontal supporting axle 22 on the protuberance 37b of skin zone 37 outside the 2nd and not outside the 1st in the skin zone 36.Therefore, the 1st outer skin zone 36 is because the load (static load) of sliding door 13 be out of shape and the impact (dynamic load) that is subjected to from rolling surface during mainly due to rolling and being out of shape hardly.Thus, can improve the withstand load, creep properties etc. of supporting roller 30.

Also can obtain the effect same with supporting roller 30 by the roller 40 that as above constitutes.And, by supporting roller 40, with the basis of the same effect of supporting roller 30 on, also can obtain following effect.Namely, in supporting roller 40, protuberance 46a1 constitutes according to the difference of circumferential position and the overhang difference, corresponding to protuberance 46a1, the degree of depth of slot part 47a1 constitutes according to the difference of circumferential position and difference, even if therefore the outer peripheral face effect at supporting roller 40 has circumferential load, can prevent that also the 2nd outer skin zone 47 from upwards misplacing in week with respect to the 1st outer skin zone 46.
And, when enforcement is of the present invention, be not limited to above-mentioned embodiment, in the scope of the purpose that does not break away from invention, can carry out various changes.
For example, in supporting roller 40, the 1st outer skin zone constitutes the periphery of the axial pars intermedia that covers outer ring 43, and supporting roller 40A as shown in figure 13 also can constitute the periphery that integrally covers outer ring 43.That is, in the section of the center of rotation axis CA that comprises supporting roller 40A shown in Figure 13, the axial two ends of the 1st outer 46A of skin zone are positioned on the axial two ends of outer ring 43.Under this situation, the 2nd outer 47A of skin zone not with outer ring 43 butts.In the supporting roller 40A that as above constitutes, the 2nd outer skin zone 47 that constitutes with hard material not with outer ring 43 butts, so compare with supporting roller 40, the impact absorbency of supporting roller 40A is outstanding.Yet the load of sliding door main body acts on the 1st outer 46A of skin zone, thus bearing roller 40A and bearing roller 40 to compare withstand load, creep properties inferior slightly.In addition, in supporting roller 30, the 1st outer skin zone 36 also can constitute the periphery that integrally covers outer ring 33.
And in supporting roller 40, the overhang of protuberance 46c1 constitutes different corresponding to circumferential position, and corresponding to protuberance 46c1, the degree of depth of slot part 47b also can constitute different corresponding to circumferential position.Thus, even if to the periphery of supporting roller 40 week upwards effect bigger load is arranged, can prevent from also that the 2nd outer skin zone 47 from making progress in week with respect to the 1st outer skin zone 46 to misplace.
And, in supporting roller 30 and supporting roller 40, the degree of depth of slot part 33a and slot part 43a constitutes according to the difference of circumferential position and difference, corresponding to slot part 33a and slot part 43a, the overhang of protuberance 36d and protuberance 46d also can constitute according to the difference of circumferential position and difference.Thus, even if the effect of making progress has under the situation of bigger load in week in the periphery to supporting roller 30 and supporting roller 40, can prevent that also crust 35 and crust 45 from upwards misplacing in week with respect to outer ring 33 and outer ring 43.
And the material of the 1st outer skin zone 36,46,46A and the 2nd outer skin zone 37,47,47A is not limit.But, as the material of the 1st outer skin zone 36,46,46A, be the following material of 2000Mpa if select spring rate, utilize the 1st outer skin zone 36,46,46A can fully absorb the impact that is subjected to from rolling surface when then rolling, the quietness when the raising door opens and closes.
