STRUT STRUCTURE OF LIFTER

摘要

PROBLEM TO BE SOLVED: To provide strut structure of a lifter which is simplified while improving strength. SOLUTION: The support structure is provided with: a lift body 13 to which a container holding part 12 is connected; a strut 14 for liftably supporting the lift body 13; and a lift mechanism 15 for lifting and driving the lift body 13. The lift mechanism 15 has: a screw shaft 28 extending to a vertical direction and rotatably provided around the axial center; a guide rail 29 extending to the vertical direction; and a slider 33 provided on the lift body 13 and slidably fitted in a nut member 32 threadedly engaged with the screw shaft 28 and the guide rail 29. The strut 14 is provided with a strut frame structure 22 having the strength of the strut 14. The strut frame structure 22 is formed in a horizontal cross sectional shape and in a shape circling the whole periphery of the outside of the lift body 13 and the lift mechanism 15.
