<P>PROBLEM TO BE SOLVED: To provide a lightweight type impact unit used for an impact assembly which has long service life, and which includes an impact part, a piston element, a transmission element, and a drive part. <P>SOLUTION: An impact part includes a cavity 202, and a piston element 21 is housed in the cavity 202. A transmission element 22 includes a first end and a second end opposite to the first end. The first end is connected to the piston element 21 and the second end is connected to a drive part 23. The drive part 23 can intermittently provide an impact force by the transmission element 22, this impact force is transmitted to the piston element 21 via the transmission element 22, and reciprocating movement is generated by allowing the impact part to impact against the piston element 21. <P>COPYRIGHT: (C)2013,JPO&INPIT |
