Shock prevention device null of the flexible pipe case in the Brush Cutter payment

摘要

PROBLEM TO BE SOLVED: To provide a vibration preventing device for pipe case for reaper with which safety and workability can be improved by preventing resistance vibrations caused by work and vibrations caused by high-speed turns by arranging, fitting and fixing plural vibration reducer pipes at prescribed positions on the outer peripheral surface of a pipe case. SOLUTION: The rotation of an engine 2A is transmitted to a shaft inside a pipe case 2B by a clutch so that a saw blade 2D can be rotated and in order to prevent the arched vibrations caused by the high-speed revolution of the shaft, 1st, 2nd, 3rd and 4th vibration reducer pipes 3, 4, 5 and 6 are arranged, fitted and fixed at the prescribed positions on the outer peripheral surface of the pipe case 2B. In this case, it is preferable that the 1st and 4th vibration reducer pipes 3 and 6 are balanced, slid toward the pipe case 2B and fixed thereafter.
