<p>A chain for three-dimensional transfer line, comprising synthetic resin chain base bodies (A) connected endlessly to each other through shaft pins (C), wherein the chain base body (A) further comprises a top plate part (A2) having a transported object placed on the upper surface thereof, and a link part (A1) located on the underside of the top plate part and having a projected head part (1) and a pair of leg piece parts (2), wherein the upper surface of the projected head part forms an arc surface having a center at the axis of a shaft pin and is smoothly connected continuously to the upper surface of the top plate part, the length of the top plate part in longitudinal direction is equal to or less than a chain pitch, a lower side inclined surface (11) is provided at the front edge portion of the top plate part, and a curved recessed part (7) having a recessed inclined surface (7a) is provided at a rear edge center portion thereof, whereby, even if an opening is formed between the top plates, a large height difference is prevented from being produced by the projected head part and thus the transported object is prevented from being pushed up, caught, or turned over.</p> |
