PROBLEM TO BE SOLVED: To provide a roller conveyer facility with a valve on a load detecting means side to which an external force is not applied in a normal detectable state. SOLUTION: Each of zones Z<SB>1</SB>to Z<SB>n</SB>is provided with an accumulator unit 25, a brake unit 30, a selector valve 71 for reversely operating the both units 25 and 30, and the load detecting means 40. The load detecting means 40 has a pair of bracket bodies 42 oscillatable about a lateral shaft core 41, a sensing roller 44 liftable between tollers 6 is mounted between the bracket bodies 42, and weight energization is performed to project the sensing roller 44 from a conveyer conveying surface 8. A normally closed on-off valve 58 facing to operating parts 42c formed in the bracket bodies 42 is disposed on a conveyer frame 3 side. When the sensing roller 44 moves against a weight energization force, the on-off valve 58 is operated to a communication state by the operating parts 42c and the selector valve 71 in an upstream side zone is switched to a brake operation side.
