Each shows a schematic side view. The pantograph type jack mechanism 10 is fixed to the floor surface of the vehicle by a pair of legs 11. Each leg 11
Links 13 and 15 are rotatably attached to the pins by pins 17 and 19, respectively. The link 13 is rotatably attached to the link 25 by the small-diameter end portion 21a of the rod 21 extending in the lateral direction, and the link 15 is attached to the link 27 by the small-diameter end portion 23a of the rod 23 also extending in the lateral direction. It is rotatably attached. The links 25 and 27 are rotatably attached to the platform 33 by pins 29 and 31. Further, between the platform 33 and the leg portion 11, four steady rests 34 for securing steady of the platform 33 are provided.

Central square portion 21b of rod 21 and central square portion 23b of rod 23
Screw holes are formed in each of the screw holes, and the screw thread portions 35a and 35b of the shaft 35 are screwed into these screw holes. Screw thread 35b
Is a reverse screw to the thread 35a, and when the lever 39 attached to the front end of the shaft 35 is rotated, the rods 21 and 23
Move toward and away from each other. The rear end of the shaft 35 is supported in a long hole 37a formed in the bracket 37, and the shaft 3
5 can move up and down. Axis 35 by slot 37a
Since the movement in the front-back direction is restricted, the rods 21 and 23 perform the same movement, and the platform 33 moves up and down uniformly. For example, rotating shaft 35 clockwise causes rods 21,23 to move closer together, platform 33 rises, and rotating shaft 35 counterclockwise causes rods 21,23 to move further apart.
The platform 33 is designed to descend.
