PROBLEM TO BE SOLVED: To make vibration of a motor difficult to be transmitted to a grip part of an operation rod and make an operator who grips the grip part of the operation rod hardly get tired due to vibration.SOLUTION: A work machine 10 includes: an operation rod 11 having a grip part which is gripped by a worker a motor 20 mounted on a rear end part of the operation rod 11 a rotary tool 32 mounted on a front end part of the operation rod 11 and rotated by the motor 20 and a power transmission shaft 12 rotationally supported inside the operation rod 11 and transmitting the drive of the motor 20 to the rotary tool 32. A mount frame 40 where the motor 20 is mounted, is integrally fixed to a back end part of the operation rod 11. The mount frame 40 is provided with elastic members 43, 44 supporting the motor 20 in a vibration isolation state.COPYRIGHT: (C)2015,JPO&INPIT【課題】原動機の振動を操作棹の把持部に伝達しにくくし、操作棹の把持部を把持する作業者が振動により疲労しにくくする。【解決手段】作業機10は、作業者が把持する把持部を有した操作棹11と、操作棹11の後端部に設けた原動機20と、操作棹11の前端部に設けられて原動機20により回転する回転工具32と、操作棹11内に回転可能に支持されて原動機20の駆動を回転工具32に伝達する動力伝達軸12とを備え、操作棹11の後端部には原動機20を搭載するマウントフレーム40を一体的に固定し、マウントフレーム40に原動機20を防振的に支持する弾性部材43,44を設けた。【選択図】図1
