Abstract
A heavy-duty power transmission V-belt includes right and left tension members having concave parts on upper and lower faces thereof, and a large number of blocks having fitting parts for compressedly fitting the tension members therein on right and left side faces of the blocks. By compressedly fitting the tension members in the fitting parts of the blocks, the respective blocks are fixedly engaged with the tension members so as to allow the side faces thereof to be brought into contact with a groove face of the pulley. An innermost lower face is formed in an innermost portion of the fitting part of each block, and an innermost lower face angle .alpha. between the innermost lower face and a vertical plane is determined so as to have a relationship of .beta.-3<.alpha.<.beta.+3 with a belt side face angle .beta.. Such angling of the faces of the blocks improves the durability of the belt by preventing occurrence of imbalanced abrasion of the tension members, suppressing heat generation in the belt, and reducing noise of the belt even when tile belt is in use for a long period of time.
