Abstract

The present invention relates to a height control device for a saddle or handlebar of a bicycle, which facilitates the control of the height of a saddle or handlebar of a bicycle, and which enables the height-controlled saddle or handlebar to be fixed without rotational movement in the axial direction. A height control device for a saddle or handlebar of a bicycle comprises: a tube guide, of which an end is integrally formed with or connected with the tube of a bicycle and the other end is coupled with a stay clamp; a post, of which an end is fixed to the saddle or handlebar of the bicycle and the other end is inserted into the tube guide so as to slide in the vertical direction; the stay clamp for fixing a clamp which controls the height of the post; and a locking pin for locking or releasing the post. The post has an indented groove formed in the longitudinal direction, and the stay clamp has a protrusion formed in the longitudinal direction at a position corresponding to the indented groove, so that the rotation of the post in the axial direction may be prevented in the tube guide.
