As shown in FIG. 11, as the locking claws 53A rotate outward, the arcuate portion of each locking claw 53A protrudes toward the edge of the mounting hole D10 to form the short side of the mounting hole D10. The flange 511 of the flat surface 51 of the mounting base 5 is pressed against the entire peripheral edge portion of the mounting hole D10 on one surface side of the mounting plate D1 (via the waterproof packing 62), The hinge blade 2 is firmly attached and fixed to the attachment plate D1. In this way, the hinge blade 2 can be securely fixed to the door D with one touch. Further, in the hinge blade 2, the hook 53 and the bearings 52 have a shape different from that of the hooks 43 of the hinge body 1 of the pair of hooks 53. Can be downsized, and can be easily attached to the side of the door near the corner.
