PROBLEM TO BE SOLVED: To provide a belt driven working machine with an adjusting mechanism for adjusting the tension of a pulley belt with the axial cores of both driving and driven pulleys held parallel to each other. SOLUTION: A reference wall 51 is erected on a frame 52 in the vertical direction. At the end of the casing of a working machine body 30, a plurality of fixed pieces 32-34 are provided having contact faces in the direction perpendicular to an input shaft 31. On the fixed piece 32, a supporting point side fixing bolt 38a is mounted which is inserted into a bolt hole 35 of the reference wall 51. On the other fixed pieces 33, 34, fixing bolts 38a, 38c are mounted which are inserted into oblong bolt holes 36, 37 of the reference wall 51, respectively. During loosening the fixing bolts 38a-38c, the working machine body 30 can be turned with the fixing bolt 38a as a supporting point. During fastening the fixing bolts 38a-38b, the working machine body 30 can be fixed to the reference wall 51 at a predetermined turn position. COPYRIGHT: (C)2009,JPO&INPIT
