Abstract
A handle bar fixing device for a bicycle, which is used to fix a handle bar to a cylindrical holding portion attached to the utmost end of a lug provided at a handle stem. At the lug is provided a through bore which extends lengthwise of the lug, opens at one end into the holding portion and at the other end onto the stem body, and has a screw thread in part. A control member with two first and second screw threads different in pitch angle and in the direction of screw, is screwed with the through bore by way of the first screw thread. A pusher having a screw member screwable with the second screw thread is supported axially movably only to a first end portion of the through bore opening into the holding portion. The control member is rotated to force the pusher to move lengthwise of the lug so that the handle bar inserted through the holding portion may be fixed thereto.
