Abstract
In a friction drive belt B, at least a contact part 13 of a belt body 10 with a pulley is made of an elastomer composition. The contact part 13 of the belt body 10 with a pulley has a large number of cellular pores 15 formed in the contact surface with the pulley.
Claims6
A friction drive belt in which at least a contact part of a belt body with a pulley is made of an elastomer composition, wherein the contact part of the belt body with a pulley has a large number of cellular pores formed in the contact surface with the pulley.
A method for fabricating a friction drive belt whose belt body is made of an elastomer composition, the method comprising the steps of:
- hot molding an elastomer composition in which hollow particles are blended, thereby forming a belt body preform;
- and cutting the formed belt body preform to form a contact part of the belt body with a pulley.
