ABSTRACT:
A cooling fan is provided on at least one of the drive pulley and the driven pulley which are drivingly coupled together by means of a belt. The casing in which the pulleys and the belt are accommodated is provided with air inlet port means and air outlet port means. Rotation of the cooling fan in unison with rotation of the pulley provided with the cooling fan causes fresh air to be forcibly sucked into the casing through the air inlet port means, and discharged to the outside through the air outlet port means after cooling the pulleys and the belt. The air inlet port means and the air outlet port means are arranged or constructed so as to prevent intrusion of dust, mud, water, etc. into the casing. Further provided are means for enhancing the efficiency of cooling the driven pulley by the fresh air drawn in as well as means for radiating heat generated within the casing through the casing walls.
