Claims

[Scope of Claim for Utility Model Registration] 1. A pillar pipe that is fitted into a vertical pipe of a bicycle frame, a saddle holding part that is attached to the upper end of the pillar pipe so as to be movable up and down and holds a saddle, and a saddle holding part that is disposed within the pillar pipe. a pull-up bolt whose upper end is fixed to the lower end of the saddle holder; a tapered mortar supported by the lower end of the pull-up bolt and pressed against the inner wall of the vertical pipe when the bolt is pulled up; and the pillar pipe or the saddle holder A bicycle saddle support comprising: a threaded groove provided on the outer circumferential surface of the bicycle; and a threaded assembly that is screwed into the threaded groove and whose rotation moves the saddle holding part up and down with respect to the pillar pipe. mechanism. 2. The bicycle saddle support mechanism according to claim 1, wherein the tapered die is formed by cutting the lower part of the pillar pipe diagonally. 3. A pillar pipe that is fitted into a vertical pipe of a bicycle frame, a saddle holding part that is attached to the upper end of the pillar pipe so as to be movable up and down and holds a saddle, and a saddle holding part that is arranged inside the pillar pipe and whose upper end is attached to the saddle holding part. A pull-up bolt fixed to the lower end; a tapered mortar supported by the lower end of the pull-up bolt and pressed against the inner wall of the vertical pipe when the bolt is pulled up; and a tapered mortar rotatably fitted to the upper end of the pillar pipe to hold the saddle. A bicycle saddle support mechanism, comprising: a rotating body that supports the saddle holding part; and a cam part that is formed on a contact surface of the rotating body with the saddle holding part to move the saddle holding part up and down. 4. The bicycle saddle support mechanism according to claim 3, wherein the tapered mill is formed by cutting the lower part of the pillar pipe diagonally.
