Abstract
A link unit includes two outer chain plates and an assembling pin. Each of the outer chain plates has a first end section, and a second end section spaced apart from the first end section. The first end section of each of the outer chain plates has a through hole. The second end section of each of the outer chain plates has 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 removably through the connecting hole of each of the outer chain plates, and is capable of being prevented from moving past the neck portion of each of the outer chain plates so as to be positioned in the second hole portion of each of the outer chain plates.
