PURPOSE:To facilitate rectilinear operating motion by combining a flat link mechanism comprising links of the same length, speed increasing mechanism having a speed increasing ratio of 1:2 and a parallel link mechanism for transmitting power to the speed increasing mechanism. CONSTITUTION:A link 2 is rotatably mounted on a base 1, and a link 4 parallel to the link 2 is rotatably mounted in the same manner. A link 5 connected to the link 4 is firmly coupled to an input shaft of a speed increasing mechanism 6 on the link 2, and an output shaft of the speed increasing mechanism 6 is firmly coupled to the link 3. As the length of the link 2 is set equal to that of the link 3, and the speed increasing ratio of the speed increasing mechanism 6 is set 1:2, the forward end of the link 3 is forced to reliably perform rectilinear motion by turning the link 2.
