Abstract
A hammer-like tool for relieving stiffness in the neck and shoulder with an improved therapeutic and prophylactic effect. A cylindrical space is provided in the head of the hammer-like tool, a free-flowing magnet provided in the cylindrical space, an induction coil provided near the periphery of the cylindrical space to surround it, a load coil provided near the face of the hammer-like tool, and a high-frequency oscillator circuit. The load coil generates a high-frequency electromagnetic wave by supplying an electromotive force to the load coil via the high-frequency oscillator when the magnet moves within the cylindrical space.
