Abstract:
1. A cable connection structure for axially connecting a first cable and a second cable to each other, wherein axial connection of the first cable and the second cable is performed by a cylindrical connection member that is constrained from axially moving, wherein a connection end portion of the first cable is provided with a radially outwardly projected engagement projection, further wherein a connection end portion of the second cable is formed with an axially extended reception groove that is capable of axially receiving the engagement projection, wherein the first cable is constructed such that when the connection end portion of the first cable is inserted axially into the cylindrical connection member from one side, the engagement projection can be axially received along an insertion groove that is formed in the cylindrical connection member, wherein the insertion groove is shaped such that an axial terminal end portion of the insertion groove into which the engagement projection is inserted is bent in one circumferential direction, and when the engagement projection reaches a terminal end position of the insertion groove, the engagement projection is maintained in a condition in which dual-directional axial movement thereof with respect to the connection member is restrained, wherein a reception groove formed in the connection end portion of the second cable is shaped such that an axial terminal end portion of the reception groove into which the engagement projection is inserted is bent in the other circumferential direction opposite to the insertion groove, further wherein when the connection end portion of the second cable is axially inserted into the cylindrical connection member from the other side thereof, the engagement projection of the first cable retained in the cylindrical connection member is axially received along the reception groove of the second cable, further wherein when the engagement projection reaches a terminal end position of the reception groove that is bent in the other circumferential direction, the engagement projection is removed from the terminal end position of the insertion groove of the connection member and as a result, the engagement projection is released from a condition in which axial movement thereof with respect to the connection member is restrained and is placed in a condition in which axial movement thereof with respect to the second cable is restrained, wherein in the condition in which the engagement projection reaches the terminal end position of the reception groove of the second cable and axial movement thereof is restrained, the engagement projection is retained in the terminal end portion of the reception groove by an axially extended portion of the insertion groove that is formed in the connection member and as a result, the cables can be axially integrally connected to each other so as to axially move while the cables are integrated with each other, and wherein the first cable is provided with a spring member that is capable of engaging the connection member and rotationally biasing the connection end portion of the first cable in one circumferential direction when the first cable is inserted into the connection member, further wherein the engagement projection provided to the connection end portion of the first cable is transferred to the terminal end position of the insertion groove that is bent in one circumferential direction by a biasing force of the spring member, so as to be elastically retained therein.
