た。Conventional technology This kind of conventional case is made by deep drawing a flat metal plate to draw out the top plate, left and right side parts, and front and rear end faces, and then, as shown in Fig. 3, for example, the built-in lock is opened. Holes for bar rods, insertion holes for metal fittings, keyholes, etc., were punched out and opened.

加工しにくいという技術的な困難もある。Problems the invention aims to solve In the former case, in which the holes are drilled after deep drawing, the surface of the case becomes rough due to the repeated drawing process and the rough edges of the openings, so it is necessary to perform surface treatment after processing. There are also technical difficulties in that it is difficult to process because the opening is formed into a case shape.

解消することができる。Function As described above, the present invention has both left and right side surfaces connected to each other on both sides of the narrowed top plate, and both front and rear end surfaces are provided in a bent shape so as to be continuous with both side surfaces and the top plate. Therefore, the corners of each surface are continuous curved surfaces. In addition, for the insertion hole of the bar rod, the insertion hole of the lock receiving metal fitting, the keyhole, etc., the notch portions are butted from the left and right while the uncut portions of the end edges of the end face are butted from the left and right to form a seam. to form a predetermined opening. Therefore, deep drawing is not required, hole punching after molding is not required, and the drawbacks of the conventional products can be overcome.

十分に備えているという実用的効果がある。Effects of the invention According to the invention configured as described above, the aperture of the case is shallower than that of conventional products, and the opening can be pre-formed by punching out the material as it is in the form of a plate. The degree of processing applied to the board is reduced, and there is no need to reapply surface finishing after processing. Therefore, while it is possible to reduce man-hours and costs, it also reduces the safety of bicycle locks, which have curved connections on each surface that forms the surface of the case, and which are often used in a fumbling manner. This has the practical effect of being fully prepared.
