Abstract:
1. A cable connection structure for axially connecting a first cable and a second cable to each other, wherein the first cable and the second cable are axially connected via 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, and a connection end portion of the second cable is provided with an axially extended reception groove configured to axially receive 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 a first side, the engagement projection is axially received along an insertion groove that is provided at 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 a circumferential direction, and when the engagement projection reaches the 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 provided at 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 an opposite circumferential direction opposite to the insertion groove, and when the connection end portion of the second cable is axially inserted into the cylindrical connection member from a second 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, wherein when the engagement projection reaches the terminal end position of the reception groove that is bent in the opposite 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, and 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 are axially integrally connected so as to axially move while integrated with each other.
