Abstract: The present invention provides a toilet bowl flushing water tank device which can largely open a discharge valve element instantaneously and, at the same time, can ensure a relatively large space in the vicinity of a discharge valve device thus enhancing a discharge capacity with a small power. A push button mounted on a tank lid body of a flushing water tank body is arranged at a position offset to one side from a position where a discharge opening is formed, a leverage device is constituted of a lever which is interlockingly connected to the discharge valve element and a pedestal which pivotally supports a middle portion of the lever. The pedestal pivotally supports a middle portion of the lever at a position closer to a push button side than the discharge valve device.

Abstract: The present invention provides a toilet bowl flushing water tank device which can largely open a discharge valve element instantaneously and, at the same time, can ensure a relatively large space in the vicinity of a discharge valve device thus enhancing a discharge capacity with a small power. A toilet bowl flushing water tank device includes a flushing water tank body forming a discharge opening in a center portion thereof, a discharge valve device for vertically moving a discharge valve element relative to the discharge opening, the discharge valve device being mounted and housed in the flushing water tank body, a leverage device being interlockingly connected to the discharge valve device, the leverage device being mounted and housed in the flushing water tank body, and a push button being interlockingly connected to the leverage device in the flushing water tank body, the push button mounted on a tank lid body of the flushing water tank body.

Abstract: A method for storing horticultural plants and an apparatus therefor are disclosed. The method of the present invention comprises placing the live horticultural plants in a container for transportation, wherein the temperature and the humidity in the container are kept at conditions suited for the horticultural plants within the range of 10.degree.-25.degree. C. and 60-90% RH, volatile gas generated by the horticultural plants are removed, the air inside the container is circulated, and the horticultural plants are irradiated with a light mainly composed of red light and blue light.
