To provide a board inspecting press device capable of remarkably increasing pressing force in relation to the board as well as capable of being miniaturized by restraining the height.

A piston rod 13 and arms 6a, 6b, 7a, 7b, 8a and 8b of respective links 6 to 8 are in a state as shown in Fig., a pressing plate 15 is stationary above a board 2. When the rod 13 is operated in the direction of an arrow R, A-arms 6a to 8a are rotated around an upper board 1a, B-arms 6b to 8b are rotated around a pressing plate attaching plate 9, rotation is generated around respective connecting points 10 to 12, and the pressing plate 15 is lowered in the direction of an arrow P. When the rod 13 reaches the terminal end, the arms 6a, 6b, 7a, 7b, 8a and 8b are made into a line, and the pressing plate 15 is brought into contact with the base plate 2 through pins 16. The moment of force to be generated on the pressing plate 15 at this time is extremely large, and therefore, pressing force to the board 2 is remarkably increased.
