PURPOSE:To stabilize a steel belt as well as improve generated frictional force by increasing a contact region between a V type pulley inner wall and a chain type steel belt. CONSTITUTION:A bush chain comprises an inner link 13, an outer link 14, a pin 15, and a bush 16. A block hole 17 is provided through a substantially central part of the inner link 13 and the outer link 14. A V block 12 in frictional contact with a V type pulley is fixed in a block hole 17. Both end surfaces 18, 18 of the V block 12 are inclined in a slant angle, and brought into contact with a V type pulley slant surface. |
