Abstract
A raising/lowering conveyance device for a container for conveying an article includes a container gripping mechanism having multiple container support pins which are arranged so as to be capable of freely protruding and retracting. A spring for biasing the container gripping mechanism upward is interposed between the container gripping mechanism and a columnar support member for supporting the container gripping mechanism such that the container gripping mechanism can be freely raised and lowered. As a result of the upward biasing force of the spring, the container gripping mechanism is held at an equilibrium height in equilibrium with the weight thereof and is capable of movement vertically with the equilibrium height serving as the center of the movement. When the container gripping mechanism lifts a container, the mechanism receives the weight of the container, descends from the equilibrium height, and is supported at the fixed height of the columnar support member.
