PROBLEM TO BE SOLVED: To surely restrict the slip of shaft pipes and movable frames toward the lower position of inclination by using a structure as simple as possible, in benches for nutrient solution culture which are inclined in the longitudinal direction. SOLUTION: Plural frames 1 are arranged in a row with proper separations and with a desired inclination in the longitudinal direction. A pair of shaft pipes 5 having almost same length as the whole length of the apparatus are supported by shaft pipe-receiving members 3 which are placed on each frame 1. Movable frames 6 are placed on the pair of the shaft pipes. A disk is attached on the shaft pipe 5 in the direction perpendicular to the shaft, the front side of the disk is received by the rear end surface of a frame 1, and a movable frame 6 is received by the backside of the disk, and thereby the slipping of the shaft pipes 5 and the movable frames 6 are prevented. |
