習具。[Scope of Claim for Utility Model Registration] 1. A space partitioned by a stopper fixed to the end of a cylinder having a required length and thickness and a slidable weight that fits into the inner diameter of the cylinder. Assume that the movement increases or decreases the air pressure in the space, and a spring that acts in the direction of expanding the volume of the space is engaged with a weight and housed inside the cylinder, and the force acting on the weight due to swing is equal to the stress of the spring. A swing practice tool that balances itself using the air pressure in the space. 2. The practice swing practice tool according to claim 1 of the registered utility model claim, which has a small diameter hole formed in the plug piece or in the vicinity of the plug piece to release the air pressure in the space to the outside. 3. The practice swing practice tool according to claim 1 of the registered utility model, which forms a flow rate adjustment valve that can adjust the air pressure in the space with a rotatable knob piece that is engaged with the plug pieces.
