Claims

[Scope of utility model registration request]

A hollow rotary shaft 7 which is forcibly driven to rotate is horizontally mounted on the body frame 1 of the vehicle V, and a pair of compression link arms 9 are fixed to both ends of the hollow rotary shaft 7, respectively. Compression links 10 and 10 are respectively connected to 9 and 9 in a vertically bendable manner so as to provide a bending compression link 11.
, 11, and the body frame 1 includes:
The proximal ends of the tension links 16, 16, which cooperate with the bending compression links 11, 11 to form a parallel link, are pivotally connected, and the load receiving platform ₃ is attached to the distal end 161 of the tension links 16, 16.
The connecting link 19,
19 are pivotally connected, and each connecting link 19, 19 and the tip of the compression link 10, 10 are rotatably connected, and furthermore, on both sides of the body frame 1, each bending compression link 11, Safety levers 33, 33 are provided, respectively, which can be engaged with each other to restrain the bending of the links 11, 11, or release the restraint, and the hollow rotation shaft 7 is further provided with a connecting rod 38 that passes through the inside of the shaft 7. The safety levers 33, 33 are supported at both outer ends of the connecting rod 38, and the bending compression link 11 is rotatably supported.
A pair of lock levers 41, 42, 1 whose operation can be controlled selectively between a restraint position and a restraint release position.
42. A loading platform tilting device in a loading platform lifting device for a vehicle, characterized in that a loading platform tilting device is integrally provided with a loading platform lifting device for a vehicle.
