Claims

[Scope of Claim for Utility Model Registration] (1) A wire support cap that fits and secures into a cap mounting hole formed in the upper pipe or other part of a bicycle frame, with the leading edge on the lower surface of the cap having the required width on the inner diameter surface of the frame. An introduction piece is integrally formed with an introduction surface formed on the inner surface to receive the end of the wire inserted into the connected frame from the cap installation hole on the other side, and converge and guide it into the wire insertion hole formed through the cap. A guide device for the built-in wire entry and exit part of a bicycle frame. (2) The cap mounting hole is provided as a long hole with the minimum length necessary for the wire introduction piece integrally provided on the underside of the wire bearing cap to pass through, and the wire introduction piece is inserted into the frame from the cap installation hole. The built-in bicycle frame according to item 1, characterized in that the cap is fitted and fixed in the cap mounting hole by rotating the entire cap, and the introduction surface of the wire introduction piece is configured to have a required width on the inner diameter surface of the frame. Guide device for wire entry and exit. (3) A ring-shaped retaining protrusion is provided on the lower surface of the flange provided on the wire support cap, and when the cap is fitted and secured to the frame, the sealing protrusion is crimped to the outer surface of the hole edge of the cap mounting hole, making it waterproof. - The guide device for the built-in wire entry/exit portion of a bicycle frame according to item 1, which is characterized by having a dustproof function. (4) The wire support cap as described in item 1 is characterized by having a ring-shaped sealing protrusion raised on the inner diameter surface of the wire insertion hole, which is crimped onto the outer circumferential surface of the wire to have waterproof and dustproof functions. A guide device for the wire entrance and exit part built into the bicycle frame.
