2) A pair of brush bodies that can freely appear and disappear from the brush body (13). These brush bodies (13) have flexible brush bristles (15) planted on a brush base (14). On the upper portions of both front and rear walls (14a) (14a), a retractable holding portion (16) is formed by connecting the projected position retaining surface (16a) and the retracted position retaining surface (16b) with an inclined surface (16c).

Reference numeral (17) is a spring for urging the brush bristles (15) of the brush body (13) in a direction to be retracted into the main body case (2).

Reference numerals (18) and (19) are first and second cams that slide on and off the protruding and retracting holding portions (16) and (16) to operate the protruding and retracting of the brush bodies (13) and (13) from the lower main body case (4). The body has projections (20) that come into contact with the retractable holding portions (16) (16), and the first cam body (18) further has an operation hole (21) in the upper case (5) of the main body.
An operation knob (22) protruding from the operation knob (22) is formed. First,
The second cam bodies (18) and (19) are connected by a connecting rod (23). When the operation knob (22) is slid to the left and right, the first and second cam bodies (18) and (19) are slid to the left and right, and the protruding portions (20) ... ) Against the urging force of the spring (17), the brush bristles (15) project from the brush body withdrawal opening (12), while sliding on the operating knob (22) to project ( When 20) is brought into contact with the submerged position holding surface (16b), the tip of the brush bristles (15) is flush with the bottom surface of the lower case (4) of the main body or slightly inside the bottom surface due to the urging force of the spring (17). The brush is retracted into the retractable opening (12).

Reference numerals (24) and (24) denote sliding bodies disposed on both left and right sides of the bottom surface of the main body lower case (4) outside the brush bodies (13) and (13). A slippery resin member having a small frictional resistance, such as a fluororesin, a polyacetal resin (Duracon), and a high molecular weight polyethylene resin, is formed in a circular shape, and is adhered to the bottom surface with an adhesive.
