Abstract
Disclosed is a power transmission chain formed of a series of articulated units, each including a number of interleaved links each having a pair of pin-receiving holes at predetermined intervals and pivotally connected to the links of adjacent units by pins loosely fitted in the pin-receiving holes. The links are engageable with sprocket teeth for power transmission and the links are formed in an assymetrical shape in the direction of the pitch line and relative to a center line through a median point between the pin-receiving holes by bulging of one of the inner flanks defining a crotch portion of the link toward the other flank, part of the links being connected in a reverse direction to provide a different mechanism from others in meshing engagement with sprocket teeth.
