Abstract: PURPOSE:To prevent putrefaction and offensive odor of water by providing a sealing member for watertightly sealing a water storage tank and a cover member, and mounting a discharge tube coupled to a self-priming pump at the member. CONSTITUTION:A cover 16 is a platelike member of the shape coincident with an opening 18 of a tank body 15, and has a baglike part 23 provided at its periphery and a packing disposed therein. Four protrusions 25 are provided at sides of the cover 16 in such a manner that the two are opposed. Lock members 26 are rotatably mounted at the protrusions 25, provided with protrusions 27 engaged with holes at sides of the member 26. Two engaging pawls 28 are provided at the members 26. A pump is a gear pump and has a self-priming to directly suck water from a water supply tank 7. That is, the water is introduced into the pump through a sucking tube inserted into the tank 7 and a tube joint member. The water is discharged from the pump via the tube from a nozzle.

Abstract: PURPOSE:To enable a concurrent storing of foods and handle operation to be carried out by a method wherein a sliding member is formed by rollers comprised of a metallic roller shaft and a ring, a lower roller is placed lower than an upper roller and abuts against a deep surface of a sliding groove and then a right and left inclination of the shelf is prevented. CONSTITUTION:Each of upper roller 3a and lower roller 3b is formed by a metallic roller shaft 3c and a ring 3d rotatably arranged in the roller shaft 3c and having some metallic balls therein. Since the roller shafts 3c of the upper and lower rollers 3a and 3b are made of metal, even if much amount of foods are placed on a shelf 1, the upper and lower rollers 3a and 3b are not inclined and a more smooth rotation of it can be attained by the ring 3d having metallic balls fitted therein. Under a stopped state of the shelf 1, the driving gear 8 and the rotating gear 9 may act as a stopper mechanism and even if the foods are placed on the shelf 1, the shelf 1 may not be lowered, but its position is kept.
