PROBLEM TO BE SOLVED: To provide a flap table capable of equalizing force to be applied to the right and left sides of a top board and minimizing the warpage of the top board and the damage of bearings by individually adjusting energization force by energization means to lift up the top board between the right and left sides.SOLUTION: A flat table includes: a top board turning support mechanism for turnably and pivotally supporting a top board between a fallen-down posture and a standing posture; and top board energization means for generating torque in the direction opposite to torque to be generated by the gravity of the top board or a portion to be linked with the turning of the top board in the top board while the top board is turnably supported by the top board turning support mechanism. The top board energization means includes two kinds of top board energization means, i.e. right top board energization means for energizing the right side part of the top board, and left top board energization means for energizing the left side part of the top board. Energization force is originally adjustable in each of the two kinds of top board energization means. |
