Abstract
Official abstract text for this publication.
A belt body ( 10 ) of a friction transmission belt (B) includes a pulley contacting portion ( 13 ) made of a rubber composition. The rubber composition forming the pulley contacting portion ( 13 ) includes an ethylene-α-olefin elastomer as a rubber component, and in the rubber composition, 10-50 parts by mass of calcium carbonate relative to 100 parts by mass of the rubber component, and carbon black whose DBP oil absorption amount measured according to the method A specified in Japanese Industrial Standards (JIS) K 6217-4 is 300 cm 3 /100 g or more are mixed.
First claim
Opening claim text (preview).
The invention claimed is: 1. A friction transmission belt, comprising: a belt body including a pulley contacting portion made of a non-coated rubber composition, wherein the rubber composition forming the pulley contacting portion includes an ethylene-α-olefin elastomer as a rubber component, and, per 100 parts by mass of the rubber component, 10-30 parts by mass of calcium carbonate whose particle diameter is 0.001-20 μm, 1-30 parts by mass of conductive carbon black whose DBP…
