Finally, a cylindrical member 32 having a one-side flange portion 32 & is attached to the mounting hole portion 4 from one side thereof, and The flange portion 32a is fastened to the outer side of the cylinder mounting reed 31. Then, the portion protruding from the other side is press-formed to form the flange portion 32b so as to be fastened to the outer side surface of the column mounting portion 3丨. Further, as shown in Fig. 7(e), around the mounting hole portion 4, the tubular member 32 is welded to the column mounting portion 31, and the slits 32c and 31a are formed. According to this, the handle 20 of the fixing member 43 is removed. In the handle 20 thus constructed, since the cylindrical member 32 joined to the attachment hole portion 40 provided at one end of the body member 3 includes the flange portions 32a, 32b, the cylindrical member 3 is formed using the thin member. It is also possible to maintain the high rigidity of the cylindrical member 32. Further, since the flange portions 32a and 32b are in a state of being buckled on the outer side of the attachment hole portion 40, the length of the tubular member 32 is the thickness of the length flange portions 32a and 32b of the attachment hole portion 40, that is, The weight of the column mounting portion 31 and the tubular member 32 can be reduced. Therefore, the rigidity of the entire shank can be maintained and the weight can be reduced. [Other Embodiments] (a) In the above embodiment, the handlebar attachment portion 34 is designed to have a split structure including the fixing member 43, but the column mounting portion 31 may be used in the same manner as the body member including the slit. 3 0 — The structure of the body composition. 98972.doc -13- 1282766 • In the above-described embodiment, 'as a bonding method, a soldering method is used (an example of a soldering method, but a usual soldering method such as electrical soldering or gas soldering may be used.)
