a roller installed at an end portion of the bracket on a slide door side and that rolls in the guide rail; a cable holder formed integrally with the bracket at the end portion of the bracket on the slide door side and that holds the other ends of the opening cable and the closing cable; and a cable guide detachably installed at the cable holder and that guides the opening cable and the closing cable, wherein the cable guide is formed to separate the opening cable and the closing cable from the bracket, and a load applied to the cable guide by tensile forces of the opening cable and the closing cable is received by the cable holder and the bracket. ### Claim 2 (depends on 1) The roller unit according to claim 1, wherein the cable guide is disposed between the other end of the opening cable attached to the cable holder and the other end of the closing cable attached to the cable holder, and the opening cable and the closing cable are guided by the cable guide in an intersecting state with each other over the cable guide. ### Claim 3 (depends on 1) The roller unit according to claim 1, wherein the other ends of the opening cable and the closing cable are pivotably held by the cable holder. ### Claim 4 (depends on 1) The roller unit according to claim 1, wherein the cable guide comprises: a guide main body that guides the opening cable and the closing cable and that is extending in a wiring direction of the opening cable and the closing cable; and two leg sections respectively extending from both ends of the guide main body in a longitudinal direction toward the bracket. ### Claim 5 (depends on 4) The roller unit according to claim 4, wherein the leg sections of the cable guide comprise retaining sections disposed and fixed between the other ends of the opening cable and the closing cable and any one of the cable holder and the bracket. ### Claim 6 (depends on 4) The roller unit according to claim 4, wherein cable introducing sections that guide the opening cable and the closing cable to the guide main body are installed at both ends of the guide main body in the longitudinal direction. ### Claim 7 (depends on 6) The roller unit according to claim 6, wherein the cable introducing sections are formed at both ends of the guide main body in the longitudinal direction and formed at both ends of the guide main body in a short direction, and are extending in the longitudinal direction and inclining toward the bracket. ### Claim 8 (depends on 1) The roller unit according to claim 1, wherein the other ends of the opening cable and the closing cable respectively comprise columnar-shaped cable ends, the cable holder comprises: cable end holding sections disposed at sides to which tensile forces of the other ends of the opening cable and the closing cable are applied; and cable hooks disposed at opposite sides of the cable end holding sections of the other ends of the opening cable and the closing cable, and outer circumferential sections of the cable ends are disposed and fixed between the cable end holding sections and the cable hooks. ### Claim 9 (depends on 8) The roller unit according to claim 8, wherein two sidewalls of the cable hooks are disposed in parallel to a direction perpendicular to the wiring direction of the opening cable and the closing cable, a distance between the two sidewalls is set to a distance which allows the opening cable and the closing cable to be inserted therethrough, and slits through which the opening cable and the closing cable are allowed to be inserted from an outside of the sidewalls in the plate thickness direction toward an inside of the sidewalls in a plate thickness direction are formed in the two sidewalls at sides opposite to the sides to which the tensile forces of the other ends of the opening cable and the closing cable are applied. ### Claim 10 (depends on 9) The roller unit according to claim 9, wherein claw sections that engage with the cable hooks are formed at the cable guide. ### Claim 11 (depends on 10) The roller unit according to claim 10, wherein the claw sections are formed to cover the slits and corner sections of slits that are at inner surface sides of the sidewalls. ### Claim 12 (depends on 4) The roller unit according to claim 4, wherein the leg sections of the cable guide are held at the cable holder together with the other ends of the opening cable and the closing cable, and slip preventing mechanisms that prevent falling of the other ends of the opening cable and the closing cable from the leg sections are installed at the leg sections. ### Claim 13 (depends on 12) The roller unit according to claim 12, wherein the other ends of the opening cable and the closing cable respectively comprise columnar-shaped cable ends, insertion holes into which the cable ends are inserted are formed in the leg sections of the cable guide, and sides of the insertion holes in leg sections, which is opposite to the sides to which the tensile forces of the other ends of the opening cable and the closing cable are applied, function as the slip preventing mechanisms. ### Claim 14 (depends on 1) The roller unit according to claim 1, wherein the opening cable and the closing cable are wired by the cable guide in a manner so that the opening cable and the closing cable are offset toward a guide rail side with respect to the other ends of the opening cable and the closing cable. ### Claim 15 (depends on 1) The roller unit according to claim 1, wherein the roller has: a horizontal roller having a rotary shaft provided in a vertical direction; and a vertical roller having a rotary shaft provided in a horizontal direction, and the cable guide is disposed between the vertical roller and the guide rail. ### Claim 16 (depends on 15) The roller unit according to claim 15, wherein the vertical roller is rotatably supported by a spindle formed integrally with the cable holder, the cable guide is detachably installed at the spindle, the cable guide is formed to surround the vertical roller and to be open at one side in an attachment/detachment direction, and the opening cable and the closing cable are wired at an opposite side of the bracket of the cable guide. ### Claim 17 (depends on 1) A vehicular opening-closing body driving device comprising: the roller unit according to claim 1; and the driving device to which the one ends of the opening cable and the closing cable are connected.
