Abstract

To provide a cable joint including a joint piece which has an good sliding property and is hardly broken. The cable joint includes a joint case 10 and a joint piece 50 . The joint piece 50 is provided with a locking part of a cable end and a cable lead-out groove 56 . A joint case side main sliding surface 21 a is formed flat, and a protrusion part 61 is provided on a joint piece side main sliding surface 60 . The protrusion part protrudes toward the main sliding surfaces 60, 21 a in a direction orthogonal to the main sliding surfaces. An apex part 61 a of the protrusion part is located at a position corresponding to the cable lead-out groove 56 in the direction orthogonal to the main sliding surfaces.

First claim

The invention claimed is:

1. A cable joint that transmits operation force of a first cable to a second cable, the cable joint comprising:
a joint case; and
a joint piece having a plurality of locking parts, to which end parts of the cables are locked, and a plurality of cable lead-out parts, from which the cables extending from the locking parts are led to outside, the joint piece sliding inside the joint case; wherein
a joint case side main sliding surface on which the joint piece slides is formed flat in the joint case, and
the joint piece has at least one protrusion part on a joint piece side main sliding surface, on which the joint case slides, the at least one protrusion part protrudes toward the joint case side main sliding surface in a direction orthogonal to the joint case side main sliding surface, and an apex part of the at least one protrusion part is located at a position aligned with a position of a corresponding one of the cable lead-out parts in the direction orthogonal to the joint case side main sliding surface.

2. The cable joint according to claim 1 , wherein
the at least one protrusion part is comprised of a plurality of protrusion parts that each has an apex part located in a direction orthogonal to a sliding direction and along the joint case side main sliding surface.

3. The cable joint according to claim 1 , wherein
the apex parts are discontinuously formed in a sliding direction.

4. The cable joint according to claim 1 , wherein
the joint piece has a base part on which at least one of the plurality of cable lead-out parts is formed, and
the at least one protrusion part expands from the base part, and has a shape in which a base part side has an enlarged area and a tip side has a reduced area.

5. A cable operation mechanism comprising:
he cable joint according to claim 1 , the first cable connected to an operating part, and the second cable connected to an operated part.
