PURPOSE:To prevent lubricating oil from being agitated by a tension pulley to raise its temperature by arranging the tension pulley at a position far away from the lubricating oil level. CONSTITUTION:A pair of rotary shafts 7, 8 are horizontally supported in parallel in a case 2, and a cog-belt 13 is laid over cog-pulleys 10, 12 fixed to both the rotary shafts 7, 8. The upper part of the cog-belt 13 is employed as loose side, and a tension pulley 14 is pressed against the upper face of the belt and arranged in the atmosphere of lubricating oil. Thus, since the tension pulley 14 is arranged on the loose side of the belt in the upper part of the case 2, the tension pulley does not make contact with the oil level and agitate the lubricating oil even during rotation, and thereby the temperature of the oil is not raised. |
