Abstract
An endless belt for power transmitting according to the present invention is a tension-type belt of links forming a chain, and has high power transmitting efficiency although it can be produced with relatively low cost. With this endless belt, the respective blocks and pins start to contact sheave sides in order near the pitch line and the pitch of biting into the sheave is made smaller so as to reduce noise. Even if the respective blocks are inclined when the endless belt bites into pulley, each block contacts the sheave sides only at projecting outer end faces formed extending over a limited area corresponding to the divided pin near the pitch line (P-P). Therefore, a total of four parts, the projecting outer end faces of the first and second blocks and a pair of the divided pins, abut the sheave side in order, in one pitch of the link chain, so as to make the biting pitch smaller and decrease polygon effects.
