<P>PROBLEM TO BE SOLVED: To provide a double-acting type plate with a simple construction and a lightweight design at a low cost capable of being used for a door of a cargo compartment and a step or the like in a conveying mobile body such as a freight car or the like and performing hinge rotation and parallel movement by a single actuator. <P>SOLUTION: The double-acting type plate includes a driving lever 20 rotationally driven by the single actuator 10, a plate body 30 rotatably connected to an operation section of the driving lever 20 and a cam mechanism 40 controlling a posture of the plate body 30. The cam mechanism 40 is so constituted that the plate body 30 is made to approximately make parallel movement by a first cam groove 41 when the plate body 30 rotates one area 1 between two rotational areas 1 and 11 set in the rotational area of the plate body 30 and that the plate body 30 is rotated by a second cam groove 44 so as to follow the rotation thereof when the plate body 30 rotates the other area 11. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
