本発明は自動二輪車のハンドル構造に関するものである
。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a handle structure for a motorcycle.
自動二輪車には、そのハンドルを左右に分割した棒ハン
ドル部から構成したものがある。このハンドルの棒ハン
ドル部は、一般にフロントフォーク上端にボルトで締付
は固定した取付ボス部を介して取付けられている。Some motorcycles have a handlebar that is divided into left and right parts. The bar handle portion of the handlebar is generally attached to the upper end of the front fork via a mounting boss portion that is fixed and tightened with a bolt.
従来、上記取付ボス部は鋳造によって製作されているこ

とを特徴とするものである。The present invention achieves the above object by fitting mounting boss parts to the upper ends of the left and right front forks fixed at regular intervals by an upper placket, and fixing the bar handle parts divided into left and right parts to the mounting boss parts, respectively. In the handlebar of a motorcycle, the boss hole of the mounting boss portion for fitting the front fork, the fastening provided on the peripheral wall are rotated respectively on the split groove and the main surface on the outside of the peripheral wall. It is characterized in that it is formed in one direction, and the attachment boss portion is formed from an extruded material.
以下、本発明を図に示す実施例により説明する。 Hereinafter, the present invention will be explained with reference to embodiments shown in the drawings.

て固定されている。FIG. 4 shows the front part of a motorcycle equipped with the handle structure of the present invention. 1.1 is a front fork arranged on the left and right, and a front wheel 4 is supported between the lower ends of these forks,
Further, both ends of the unit are fixed at a constant interval by an upper bracket L2 and a lower bracket (not shown), so that they can rotate left and right about the steering shaft 3. At the negative ends of the left and right front forks 1.1, rod handle portions 5.5 divided into left and right sides are fixed via attachment boss portions 6.6.
第１，２図は、−１ユ記棒ハンドル部５の取付ボス部６
による取付構造の詳細を示ものである。Figures 1 and 2 show the mounting boss part 6 of the bar handle part 5 marked -1.
This figure shows the details of the mounting structure.
取付ボス部６は、周壁の一部に内側のボス孔６ａから外

With this configuration, the boss hole 6a, the groove 7, and each outer surface of the peripheral wall are formed parallel to the same direction as the axial direction of the boss hole 6a.

is provided so as to pass through it. In addition, both open wall portions 8,
Although a bolt 16 for tightening between the parts 9 and 9 is auxiliary provided, this bolt 16 can be omitted in the case of a relatively small motorcycle.

ができる。In the above structure, the bolt 12 in the support hole 11 is threaded into the nut 13 fixed to the tip of the rod handle 5 supported in the support hole 10, and when the bolt 12 is rotated, the rod handle 5 is pulled closer. At the same time, both peripheral wall portions 8.9 marked - are tightened so as to approach each other. By this tightening operation, the bar handle portion 5 can be fixed to the mounting boss portion 6, and the mounting boss portion 6 can be fixed to the tip of the front fork l at the same time.

ができる。The mounting boss portion 6 has a boss hole 6a and a split groove 7 as described above.
Since each surface on the outside of the peripheral wall is formed parallel to the same direction as the axial direction of the boss hole 6a, it can be molded from an extruded material 60 as shown in FIGS. 3A and 3B. Zunawachi,
This extruded material 60 is made by extruding a metal material such as an aluminum cam from a nozzle having a cross-sectional shape as shown in FIG.
Since it is molded in the same direction as the axial direction of a,
If we cut this at point C corresponding to the height h of the mounting boss 6, what will happen? Several m mounting boss portions 6 can be cut out.

Therefore, there is no need for special post-processing of boss holes and grooves, unlike conventional mounting boss portions made of cast products.
