PROBLEM TO BE SOLVED: To provide a roller conveyor facility capable of orderly and neatly arranging a plurality of pipes with good appearance by separating a piping port in every function, not requiring a decorated plate and realizing reduction of cost of the whole. SOLUTION: An accumulator unit 30 for connecting/disconnecting a conveyor driving means 10 to/from a group of rollers 6; a brake unit 40 for performing abutting/leaving action relative to the group of rollers; and a stock detection means 50 provided with an opening/closing valve 68 are provided on respective zones Z<SB>1</SB>-Z<SB>n</SB>. An inlet side port of the respective opening/closing valve is connected to a main feeding pipe 150 side for an operation fluid A. A solenoid selector valve 149 is provided on the zone Z1 in the most downstream and valve units 70 for reversibly operating both units are provided on the respective zones except for the zone of the most downstream. The valve unit is constituted by a receiving body 71 connected to the main feeding pipe; a selector valve element 81 for reversibly feeding the operation fluid from the receiving body to both units side; a coupling body 101 for sorting/feeding the operation fluid from the selector valve element to both units side; and a sorting valve element 111 capable of feeding the operation fluid to the selector valve element by opening of the opening/closing valve in the same zone.
