ABSTRACT:
A kendo dummy comprises a trunk and an oscillating mechanism. The trunk supported by a supporting frame comprises a throat piece, a breast plate and a stomach plate. There are three buzzers provided respectively behind the throat piece, the breast plate and stomach plate. The buzzers will make sound when the kendo exerciser makes an effective thrust at the throat piece, the breast plate or stomach plate. The oscillating mechanism securedly connected to the lower portion of the trunk by a stationary member, comprises a shaft secured to the stationary member, an oscillating arm pivotally mounting on the shaft, a weight suspended beneath the shaft, a torsion spring between the stationary member and the oscillating arm, a rotating member sleeved on the shaft, and a bamboo sword connected to the rotating member. With the spring member and weight, the bamboo sword when subjected to the kendo exerciser's attack will oscillate clockwise and counterclockwise.
