Abstract

A link unit includes two first chain plates and an assembling pin. Each of the first chain plates has a first inner end section, a first outer end section misaligned from the first inner end section, and opposite inner and outer side surfaces. The first outer end section of each of the first chain plates is formed with a connecting hole that has a first hole portion, a second hole portion, and a neck portion located between the first and second hole portions. The assembling pin is inserted through the connecting hole of each of the first chain plates, and is prevented from moving past the neck portions of the first chain plates so as to be positioned in the second hole portions of the first chain plates.
