PROBLEM TO BE SOLVED: To provide a light weight attachment by using an oscillatable bracket including an elastic push, and setting an attraction surface of a deflectably mounted magnet to be as high as a blade or the bottom of a frame. SOLUTION: An attachment is tilted, a clearance between an attraction surface of a magnet and a lying iron plate is reduced, and shock is absorbed during a stopping and an operation by embedding an elastic push 12 into a bracket 3. A magnet 8 is mounted an iron plate 7 into which two frames arranged in parallel are penetrated and inserted from its side, and this iron plate 7 is not fixed to the frames, so that the magnet 8 can deflect according to the lying iron plate 9. Using the principle of a lever reversely, the lower part of a blade 6 mounted to the ends of the frames and a claw-like structure portion on the opposite side are set to be as high as the attraction surface of the magnet 8, and two points of them are used as fulcrums to hardly separate the lying iron plate 9. Thus, a magnetic force required for lying work can be decreased, and a light attachment can be provided.
