1. A blade attachment tool, comprising:
a first support member supported by a pressing support portion supporting a blade formed of an elastic member that is configured to wipe liquid spreading on an abutment surface or scrape solids spreading on the 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; wherein
as the energizing member, at least one pair of compression coil springs each having one end joined to the first support member and another end joined to the second support member is provided.
