号）。[0005] When brushing the inside of the conduit of the endoscope, the state shown in FIG. 5 is prevented, that is, the tip of the brush bristles 2 is fixed to the inner peripheral surface of the conduit 10 and the brush protecting member. The brush bristle 2 and the brush protection member 5 are spaced apart from each other so that the brush bristles 2 and the brush protecting member 5 are not sandwiched between the brush 5 and the outer surface of the brush 5 (see Japanese Utility Model Publication No. 3-10730).

したがって次第に長く形成したものである。In order to achieve the above object, a brush for cleaning the inside of a pipe of an endoscope according to the present invention is provided with brush bristles protruding from a brush shaft arranged at a distal end portion of an operation shaft. In an endoscope cleaning brush in which a brush protection member is provided on the front side or the rear side of the brush bristles, the length of the bristles closest to the brush protection member is determined by the length of the bristles. In addition to forming a length that does not overlap the outer surface of the brush protection member even if it falls down, the length of brush bristles at other positions,
In a range where the brush bristles do not overlap with the outer surface of the brush protection member when the brush bristles fall, the brush bristles are formed to be longer as the brush bristles are separated.

よい。According to the present invention, the length of the brush bristles closest to the brush protection member is formed so as not to overlap the outer surface of the brush protection member even when the brush bristles fall. The length of the brush bristles at the position, within a range that does not overlap the outer surface of the brush protection member when the brush bristles fall, gradually increases as the brush bristles are separated, so that the brush bristles are connected to the conduit. There is no need to leave a wide space between the brush bristles and the brush protection member in order to prevent the brush shaft from being caught between the brush protection member and the brush protection member.
