<p>PURPOSE:To adjust the position of a tension pole and to set the tension of a brake band with high accuracy and satisfactory operability by fitting the brake band and a tension spring to a band plate which is fixed to a tension arm so as to be turned. CONSTITUTION:A tension spring 58 and a brake band 61 are fitted to a band plate 53. Accordingly, after a tension arm 50 is fixed in a prescribed position, turning force is applied to the band plate 53 by the elastic force of the tension spring 58 and the prescribed tension is applied to the brake band 61. Then, the band plate 53 can be fixed to the tension arm 50 in this turned and displaced position. Thus, the position adjustment of a tension pole 52 and the tension set of the brake band 61 can be respectively, independently executed. Thus, even when the tension arm, etc., is set to a small dimension, work easily is executed to adjust the position of the tension pole and to set the tension of the brake band.</p> |
