To provide a conveyer apparatus, safely reloading works without stopping an assembling line.

This conveyer apparatus is composed of: a guide rail 3 disposed like a loop stretching between a machining area 1a for machining a work and a reloading area 1b for reloading works; a truck 2 moved along the guide rail 3; a machining area chain 4 on the machining area 1a side, which is provided along the guide rail 3 to supply power for moving the truck 2; a reloading area chain 5 on the reloading area 1b side for supplying power for moving at a higher speed than the machining area 1a; first and second engagement mechanisms where the engagement parts formed on the truck 2 and the chains 4, 5 are engaged to transmit power to the truck 2 in the machining area 1a and the reloading area 1b; and a power interrupting mechanism for temporarily stopping the transmission of power of the second engagement mechanism to stop the truck 2 in the process of work reloading operation in a work reloading position.
