Abstract
A brush flatter is detachably attachable to a tip portion of a shaft of a drawing instrument having a brush member at the tip portion thereof. The brush flatter is provided with a casing having a space to allow the brush member of the drawing instrument to pass in an axial direction of the shaft, a shaft fitting portion formed at a proximal end portion of the casing, the shaft fitting portion having such a configuration as to fittingly seat on the tip portion of the shaft of the drawing instrument, and a brush pressing portion formed at a distal end portion of the casing, the brush pressing portion defining a slit-like opening through which a tip portion of the brush member pressedly passes so that an exposed tip portion of the brush member comes into a flat form when the shaft fitting portion of the casing fittingly seats on the tip portion of the shaft of the drawing instrument. A drawing instrument is attached with such brush flatter.
