Abstract

PURPOSE: For improving safety without affecting the ease of replacing a belt, to place a driving side pulley and a follower side pulley as well as said belt between an arm and a frame.
CONSTITUTION: A follower side pulley 8 is provided between an impellor 7 and an impellor shaft 6 supporting means 5, the driving side pulley 12 of a motor 10 is directed to said impellor 7, and a belt 13 is fitted on said both pulleys 8 and 12 so that formula L>2l1+πl2 may be satisfied wherein the rotation radius of the outermost end of said impellor 7 is l1 and the radius of said impellor shaft 6 is l2. Thereby, said belt is within said frames 2 and 3 for safety and can be easily taken out after passed under said impellors by passing the blades of said impellor 7 one by one inside said belt 13 after detaching said belt 13 from said both pulleys 8 and 12.
