PROBLEM TO BE SOLVED: To prevent positional displacement of a rim-mounting-type urine sampling unit during a user's standing action or sitting action onto a western-style stool, by improving effective sliding resistance between a rim of the western- style stool and the rim-mounting-type urine sampling unit by a sliding resistance improving means. SOLUTION: A rim itself of a western-style stool or a rim-mounting-type urine sampling unit itself is constituted with a material high in sliding resistance. In other words, rubber or suction cups 651 are mounted to a portion in contact with the rim of the western-style stool. The rubber or the suction cups 651 are used for preventing backlash when a user sits on the stool. A component or a member which is high in coefficient of friction is mounted to increase a slid stopping effect to prevent sliding between the rear surface of the rim- mounting-type urine sampling unit and the rim of the western-style stool. Position where the rubber or the suction caps 651 are a part under an abutting part of a cushion (stool leg portion) of the stool, and thereby, weight of the user applies to the rubber or the suction cups 651 to further improve the slid stopping effect.
