Description of the Invention (1) [Technical Field to which the Invention belongs] The present invention relates to a rod-shaped vehicle used by a driver to control the direction of a small vehicle such as a locomotive, a motor tricycle, etc. Handle ° [Previous technology] In general, handlebars are used to process the handlebar tube body using a bending machine. The handlebar and steering shaft (mandrel tube body) are welded to a connector made of pressure-processed sheet material. Mostly, for the sake of strength, a bridge bar member is used to bridge between the two grip parts. However, the bridge bar member is easy to bend, so it is bound to avoid the interference with the bridge bar member and set up another bracket. Thus, there has been an example in which the center clamp portion of the handle pipe body of the handlebar is made thicker than the grip portion, and is gradually reduced to the shape of the grip portion by a tapered reduction portion (Japanese Patent Application Laid-open No. Heihei 4 — 2 7 4 9 8 5) and so on. In order to form the above-mentioned shape, in this example, the handle pipe body is formed with the upper and lower halves facing each other, and each of them is pressure-processed to form a hollow structure, or a high-pressure liquid is injected into the closed pipe body, and the pipe is The body is produced by press forming, for example, a lower mold and an upper mold. [Problems to be Solved by the Invention] In the former method, the upper and lower halves are separately press-processed and assembled at the same time, and the welding process requires a large number of processing workers. The latter method requires special pressure processing. That's the kind. It is necessary to install a bracket when combining with the mandrel tube body, and the number of components is also quite large.

Description of the invention (2) The present invention is made in view of the above situation, and its purpose is to provide a small number of components that are easy to process and form. Can get full strength handlebars. [Means for solving problems and effects] In order to achieve the above-mentioned object, the present invention is to form a plate-like member into a U-shaped cross-section and to integrally form a handlebar for a mounting portion of a steering shaft of a vehicle. By. Because the plate-like member is formed into a slightly rod-like relationship with a U-shaped cross-section, it can be formed by pressing. In addition, the cross-section has a chevron shape to ensure strength. Then, the mounting portion of the steering shaft of the vehicle is also formed into an integrated relationship, the number of components is small, and the assembly operation is easy. The invention of the second scope of the patent application is characterized in that, in the handlebar of the invention of the first scope of the patent application, a flange portion is formed along the U-shaped opening surface of the cross-section of the handlebar. The flange portion can be formed integrally with the body at the same time, and at the same time, the flange portion can be further enhanced in strength while being easily processed. The invention of the third scope of the patent application is characterized in that the handlebar of the invention of the first or second scope of the patent application is characterized by the left and right divided into two halves. Large-scale press equipment is not required, and the processing of the left and right halves is easy 'and sufficient strength can be ensured. The invention of the fourth scope of the patent application is that in the handlebar of the invention of the first or the second scope of the patent application, the handlebar is integrally formed with the handlebar -11--I ^-I ------ · 1ι Order! !!线-^ {Please read the precautions on the back before filling this page) This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) -5-

Description of the invention (3) The pole mounting part is its feature. The conventional structure for mounting a handle bracket for the installation of a handle rod separately by aluminum casting is that the bracket itself needs to be exquisitely finished, the drilling, tapping and the like are expensive, and it must be locked and fixed to the handle pipe body. Components such as straps require management parts and a large number of assemblers. However, the handlebar mounting portion is integrally formed on the handlebar, which eliminates the need for parts management and assembly operations, which can reduce costs. The invention of claim 5 is characterized in that, in the handlebar of the invention of claim 4, the handlebar fixing part is integrally formed with the handlebar. The integration of the handle bar mounting portion and the operation cable fixing portion with the handlebar eliminates the need for parts management and assembly operations, which can reduce costs.

When the left and right halves 5 1 L and 5 1 R are to be mated, the convex portion 5 2 b is fitted into the small hole as shown in FIG. 16, so that each other can be used without using a positioning mold. Positioning structure ° Also, the central portion of the mandrel mounting portion 5 2 is formed to be partially flat, and there is a corresponding portion of the mandrel mounting portion 5 2 of the other right half body 5 1 R. There are also round holes 5 2 c —. The arm portion 5 3 extending from the mandrel mounting portion 5 2 is continuous to the mandrel mounting portion 5 2, and its cross-section is U-shaped with an upper opening. The open end edge is bulged to form a slightly vertical upright. 5 3 a (refer to Figures 11 and 14). The root portion of the grip portion 54 is U-shaped in cross section (refer to FIG. 15), and the grip portion system has a cylindrical shape. The consumer right cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs printed the right-side half 51R and the left-side half 51L described above in a slightly left-right symmetrical shape. Using the aforementioned method, the fitting of the convex portion 5 2 b with the small hole was used to determine the At the same time as the positions of the mandrel mounting portions 5 2 and 5 2, they are combined into one body by butt welding or tightening. The combined mandrel mounting portions 52, 52 are formed in a cylindrical shape, and are inserted into the mandrel tube body 60 and combined. The mandrel pipe body 60 is shaped like the mandrel pipe body 10 in the previous embodiment (refer to FIG. 9), and the small diameter portion of the mandrel pipe body 60 is fitted into the mandrel mounting portion 5 2, 5 2 In the formed cylindrical part, as shown in Figure 16, the paper size is applicable to the Chinese National Standard (CNS) A4 (210 X 297 mm) -10- A7 436444 __B7___ 5. Description of the invention (8) (Please read first Note the item “$” on the back and fill in this page again), so that the mounting holes of the small diameter part are consistent with the bolt penetration holes 52 c and 5 2 c ′ of the mandrel mounting part, and fit the collar to the round hole. At the same time, the mandrel tube body 60 is pressed at the same time, the bolt 6 2 is penetrated from the left side, and the front end screw nut 6 3 is protruded from the collar 6 1 to the right side and locked. This handlebar 50 is a combination of the left and right halves 5 1 L, 5 1 R. Each half 5 1 L, 5 1 R is manufactured by pressing to form a U-shaped cross section. Pressing 5 1 L and 5 1 R half-presses separately can eliminate the need for large press equipment. In the case of using a surface-treated steel sheet for press working, no post-processing treatment is required. The arm portions 52, 52 have a U-shaped cross section and are further provided with the relationship of the flange portions 5 2 a, 5 2 a, so that sufficient strength can be secured. With reference to Figure 17 and Figure 26, the handlebar 7 1 in still other embodiments is described below. This handlebar 71 is also integrally formed by pressure processing a steel plate that has been surface-treated in advance. Its plane is regarded as shown in FIG. 17 and the rear view is shown in FIG. 18. The Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs printed the central arm mounting section 7 2 to the left and right boom sections 7 3 and 7 3. The left and right ends extend obliquely above the front and extend horizontally, and then extend after a few rear bends. 'Grips 7 4' 7 4 ° are formed at the left and right end portions. Then, the handle levers 8 2 '8 0 and the like are extended forward from the outer portions of the bent portions 73 a, 73 a of the arm portions 73, 73.
