ENGINE-DRIVEN WORKING MACHINE

摘要

PROBLEM TO BE SOLVED: To effectively protect an engine and a working machine by a frame of simple and lightweight structure and to suppress the vibration of a control box in an engine-driven working machine with the engine and the working machine supported in a buffered manner to the frame of framework structure through a vibration control member. SOLUTION: A main frame 12 is provided with a pair of lower frame parts 12a laterally extending on both sides of the lower parts of the engine E and working machine G; a pair of first inclined frame parts 12b connected in a bent state to one ends of both lower frame parts 12a and inclined upward toward the other end side of both lower frame parts 12a; and a pair of second inclined frame parts 12c connected in a bent state to the upper ends of both first inclined frame parts 12b and inclined upward toward one end side of both lower frame parts 12a. A control box 14 is supported to a box support member laid between the pair of second inclined frame parts 12c and to a bent connection part of the first and second inclined frame parts 12b, 12c on one side.
