Title: Belt for continuously variable transmission
Inventor: OKANO TAKEMASA
IPC: F16G5/16
Filed: 2001-10-19
Abstract: PROBLEM TO BE SOLVED: To reduce a lateral load applied to a nose when a metal element bites a drive pulley without increasing a load applied on a metal ring assembly. SOLUTION: At a front and a rear surfaces of the metal element 32, the nose 43f and a hole 43r to be engaged with each other are formed. Relation between a first clearance C1 between the nose 43f and the hole 43r and a second clearance C2 between a lower surface 45 of an ear part and an upper surface of the metal ring assembly 31 is set to satisfy 1.7<C2/C1<6.5.
