To provide a belt conveyor wherein assembly is simplified, adjustment is dispensed with, substantial cost reduction is achieved by means of kit sales and user-dependent assembly, and hygienic management capability is enhanced since whole washing and disassemly/cleansing are facilitated.

This kit of a module belt conveyor is equipped with a motor pulley 100, motor pulley support legs 200, sub-members 300 such as a driven pulley, sub-member support legs 400, a frame 500 for connecting the pulley support legs with the sub-member support legs so that a center axis 130 of the motor pulley is parallelized to a center axis 310 of the sub-members and the distance between the two axes becomes a prescribed dimension, rails 600 laid between the pulley support legs and the sub-member support legs so as to support an outward-side module belt 700 by its lower side, and module belts wound around the motor pulley and the sub-members.
