A fluid pressure transmission device is equipped with a plurality of driving fluid pressure cylinders 371, 372, a plurality of driven fluid pressure cylinders 23, 24 with cylinder chambers 23a, 24a thereof being communicated with cylinder chambers 3711, 3712 of the main driving fluid pressure cylinders 371, 372 via fluid pressure transmission pipes 381, 382, and a sub driving fluid pressure cylinder 41 which is divided into two cylinder chambers 41a, 41b by a piston 412, and the fluid pressure generated by the main driving fluid pressure cylinders 371, 372 is transmitted to the driven fluid pressure cylinders 23, 24. Pistons 3711, 3712 are driven by the main motor 40, and the piston 412 is driven by the assistant motor 43. The fluid pressure transmission pipes 381, 382 and the cylinder chambers 41a, 41b of the sub driving fluid pressure cylinder are connected via connecting pipes 421, 422. |
