<p>PROBLEM TO BE SOLVED: To provide an air spring type implantation tool for implanting an implantation device by returning an impact piston to a top dead point with a motor as a drive source, and by using compressed air in an impact piston upper chamber generated at the time, for moving downward the impact piston, in which the implantation tool included an air tank for supplying the compressed air to the impact piston upper chamber conventionally, so that maintenance performance for replacing the air tank was not good, therefore maintenance performance of the implantation tool has to be improved.SOLUTION: A pump part 40 on which a supply air generation chamber 43 for generating compressed air by downward movement of an impact piston 16, is provided. The compressed air generated in the supply air generation chamber 43 is supplied to an impact piston upper chamber 25 via a check valve 42 and a supply air recirculation passage 44. Because the pump part 40 is disposed inside, a conventional air tank can be omitted.</p> |
