Abstract

Official abstract text for this publication.

A roller unit to which a cable end of a cable pulled by a door actuator is attached moves with a slide door along a guide rail on a vehicle body, and includes: a coupling part coupled to the slide door; a guide roller supported by the coupling part and moving along the guide rail; a guide pin fixed to the coupling part and inserted into the cable end; and a fastener fastening the cable end to the guide pin. A recess is formed toward an end of the guide pin. An external diameter of the end of the guide pin is smaller than an internal diameter of the shaft hole of the cable end. The fastener includes a supporting part supporting the cable end and a protrusion part engaged with the recess.

First claim

Opening claim text (preview).

The invention claimed is: 1. A roller unit to which a cable end of a cable to be pulled by a door actuator is attached, the roller unit movable together with a slide door along a guide rail provided on a vehicle body, the roller unit comprising: a coupling part being coupled to the slide door; a guide roller being supported by the coupling part and movable along the guide rail; a guide pin being fixed to the coupling part, the guide pin being inserted into a shaft hole of the cable end; and a fastener fastening the cable end to the guide pin, the fastener being inserted in the cable end and disposed on a leading end part of the guide pin, wherein a recess is formed in the guide pin at a distal end of the leading end part of the guide pin, an external diameter of the leading end part of the guide pin is smaller than an internal diameter of the shaft hole, and the fastener includes a supporting part which axially supports the cable end at the leading end part of the guide pin, the supporting part forming a ring-shaped flat plate at an end of the fastener, a bearing part which extends axially parallel to an axis of the guide pin from a radially internal end of the supporting part, and a protrusion part to be engaged with the recess, the protrusion part protruding radially inward toward the axis of the guide pin from the internal end of the supporting part. 2. The roller unit according to claim 1 , wherein the fastener is disposed between the guide pin and the cable end and the bearing part allows relative rotation of the guide pin and the cable end. 3. The roller unit according to claim 2 , wherein the recess is a circumferential groove formed along a circumference of the guide pin. 4. The roller unit according to claim 3 , wherein the guide pin supports the guide roller on a first side of the coupling part and supports the cable end on a second side of the coupling part. 5. The roller unit according to claim 2 , wherein the guide pin supports the guide roller on a first side of the coupling part and supports the cable end on a second side of the coupling part. 6. The roller unit according to claim 2 , wherein the guide pin includes a restricting wall disposed at a proximal end of the leading end part of the guide pin. 7. The roller unit according to claim 2 , wherein the fastener includes a holding part that, together with the supporting part, sandwiches the cable end therebteween. 8. The roller unit according to claim 7 , wherein the recess is a circumferential groove formed along a circumference of the guide pin. 9. The roller unit according to claim 7 , wherein the guide pin supports the guide roller on a first side of the coupling part and supports the cable end on a second side of the coupling part. 10. The roller unit according to claim 7 , wherein the guide pin includes a restricting wall disposed at a proximal end of the leading end part of the guide pin. 11. The roller unit according to claim 7 , wherein the recess is defined as a first recess, and the guide pin includes a second recess which is disposed at a proximal end of the leading end part of the guide pin and which is engageable with the protrusion part. 12. The roller unit according to claim 11 , wherein the guide pin includes a restricting wall disposed at the proximal end of the leading end part of the guide pin. 13. The roller unit according to claim 12 , wherein the guide pin supports the guide roller on a first side of the coupling part and supports the cable end on a second side of the coupling part. 14. The roller unit according to claim 11 , wherein the first recess is a circumferential groove formed along a circumference of the guide pin. 15. The roller unit according to claim 11 , wherein the guide pin supports the guide roller on a first side of the coupling part and supports the cable end on a second side of the coupling part. 16. The roller unit according to claim 1 , wherein the guide pin includes a restricting wall disposed at a proximal end of the leading end part of the guide pin. 17. The roller unit according to claim 1 , wherein the guide pin supports the guide roller on a first side of the coupling part and supports the cable end on a second side of the coupling part. 18. The roller unit according to claim 1 , wherein the recess is a circumferential groove formed along a circumference of the guide pin. 19. The roller unit according to claim 18 , wherein the guide pin includes a restricting wall disposed at a proximal end of the leading end part of the guide pin. 20. The roller unit according to claim 18 , wherein the guide pin supports the guide roller on a first side of the coupling part and supports the cable end on a second side of the coupling part.
