(Prior Art) The frame of a scooter type motorcycle is generally of a type in which two rear pipes are connected to one main pipe extending from the head pipe to the lower rear, and an engine suspension bracket is attached at an appropriate position of the rear pipe. In addition, it is also known to use a rectangular tube-shaped connecting body in which a plate is bent for each of the left and right rear pipes at the connecting portion between the main pipe and the left and right rear pipes (Japanese Patent Publication No. 57-114776).

(Means for Solving the Problems) According to the present invention, since the connecting body of the main pipe and the rear pipe is formed by the connecting body surrounding both pipes, the connecting body is connected so that the bending moment applied to the connecting body is received by the entire connecting body. Avoiding the concentration of stress on the local area of the body, and also by using the welding flange, the rear pipe receiving groove, the engine suspension bracket, etc., which were provided on this connecting body, as the shell reinforcing body, The means is extended upward from the rear end side of the main pipe along both left and right sides of the front shell and the rear shell, which are fixed through the rear end of the main pipe to form a hollow connection body, and the upper side. Form the receiving grooves of the rear pipe located below the central part of the rear pipe, and weld the flanges formed on the upper and lower sides of the front and rear shells and the rear shell to join the two shells together. Both It is characterized in that a portion protruding from the end of the shell is welded to both shells.

Since the connection body (5) of the present invention has the above configuration,
At the welded portion with the main pipe (3), stress is generated over the entire outer circumference of the main pipe insertion holes (16), (24) to support the main pipe, avoiding concentration of stress and withstanding a large load. be able to. For example, when a clockwise moment acts on the main pipe (3), compressive stress is generated in the upper half of the outer periphery of the insertion hole (16) in the front wall (12), and tensile stress is generated in the lower half. At the same time, however, stress is generated in the outer periphery of the insertion hole (24) of the rear wall (17) in an upside-down relationship with the front wall, and the entire outer periphery of the insertion hole of the front wall (12) and the rear wall (17), that is, both walls. Since the load is supported on the entire surface of the, the concentration of stress is avoided and a strong resistance force is generated.
Further, at the connecting portion with the rear pipe (4), pipe receiving grooves (15), (20) much longer than the diameter of the main pipe are formed, and the long receiving groove supports the rear pipe.
By supporting the two receiving grooves (15) and (20) from the front and rear, stress concentration can be avoided here as well. Further, the pipe receiving grooves (15), (20), the brackets (21), (22), the bottom plate (23), etc. serve as reinforcing ribs to increase the rigidity of the connection body (5) against bending, and thus a relatively thin plate material. High strength can be obtained even by using. And the bracket (21), (2
Since 2) also serves to suspend the engine, it is not necessary to attach a separate bracket to another location on the rear pipe (4).

(Effects of the Invention) As is apparent from the above description, according to the present invention, since the connector is formed in a hollow shape by the front shell and the rear shell, it is lightweight and has high rigidity, and is easy to manufacture. is there. Since the main pipe is welded at two positions separated from each other, the front shell and the rear shell, stress can be prevented from concentrating on the connecting portion of the main pipe. Since the upper and lower ends of the receiving groove of the shell are welded, both shells serve as a strength member for the rear pipe, and stress is prevented from concentrating on the connecting portion of the rear pipe.
