A blade attachment tool includes a first support member supported by a pressing support portion supporting a blade formed of an elastic member configured to wipe/scrape liquid/solids spreading on an abutment surface by being pressed against the abutment surface and being long in one direction such that the blade is pressed against the abutment surface with a predetermined pressing force, a second support member supported to swing about a swing shaft extending in a longitudinal direction of the blade with respect to the first support member and configured such that a base end side of the blade is attached thereto, and an energizing member configured to apply a reaction force to a friction force that causes the second support member to swing about the swing shaft with respect to the first support member when the blade is pressed against the abutment surface to slide relatively to the abutment surface.

An inner peripheral surface of a belt is cogged so that cogs extend in a belt width direction and are arranged adjacent to one another at regular intervals in a belt length direction. A tip portion of the cog and a bottom portion of a groove formed between the cogs have curved surfaces each having an arc-shaped cross section. A curvature radius of a cross-sectional shape of the bottom portion of the groove is set to be larger than a curvature radius of a cross-sectional shape of the tip portion of the cog.
