摘要： PROBLEM TO BE SOLVED: To facilitate leg installing work, reduce a loss, and shorten molding time by integrally forming thick installing parts on an under surface of a bathtub in the shape of being divided into three pieces or more in the width direction of the bathtub in response to a wide leg arranged on the under surface of the bathtub. SOLUTION: A bathtub 1 is molded by injection of resin, and a wide leg Fw is installed by an adhesive on under surfaces of installing parts 2 integrally connected to its under surface. These installing parts 2 are formed in the shape of being divided into at least three pieces in the width direction of the bathtub 1, and a part between the installein parts 2 is formed as a recessed part 3 of the bathtub 1 to the bottom wall 1b side. The under surfaces of the respective installing parts 2 are also formed as the same plane so as to become parallel to a floor surface on which the bathtub 1 is arranged, and leg positioning ribs 4 are protrusively arranged in both end installing parts 2 and 2. In this way, since the volume of a thick part of the installing parts for the wide leg Fw can be reduced by dividing the installing parts 2 into three piece or more in the width direction, a resin material can be reduced, and hardening time can also be shortened.

摘要： PURPOSE: To obtain an artificial marble having improved workability, uniformity, deepness of the appearance and designability by adding calcium carbonate having a specific primary particle diameter. CONSTITUTION: Calcium carbonate having a primary particle diameter of 0.01-0.5μm and optionally surface-treated with 1-10 pts.wt. (based on 100 pts.wt. of the calcium carbonate) of a fatty acid and/or a fatty acid soap is mixed with white marble, silica, mica, cured resin, etc., and the mixture is roughly crushed. The roughly crushed material is compounded to a resin in an amount of 0.1-50 pts.wt. based on 100 pts.wt. of the resin and the mixture is optionally incorporated with a filler, a curing catalyst, a cure accelerator, a shrinkage controlling agent, a stabilizer, a colorant and a thickener, kneaded and formed by casting.
