To provide a simplified construct of a surgical table.

This surgical table is prepared with a crutch (15) for adjusting the positional relation between boards (7) and (8) connected via a pivot (12), wherein the crutch (15) comprises a support plate (14) connected to the board (8), a plurality of engagement holes (16) circularly bored on the support plate (14) around the pivot (12), and a clamping screw bar (17) mounted on the board (7) engageably to any one of the engagement holes (16). The table allows to adjust the position of the board (8) or another board (7) by rotating around the pivot (12) and fix the positional relation between the boards (7) and (8) by inserting the clamping screw bar (17) into any one of the engagement holes (16) on the support plate (14).
