BLADE ATTACHMENT TOOL AND BLADE SUPPORTING STRUCTURE

WIPO Patent Application WO/2020/162234

A1

An attachment tool 10 is provided with: a first support member 11 supported by a wiper arm which supports, so as to be pressed against an abutment surface 2 at a prescribed pressing force, a unidirectionally-long blade 3 that is made of an elastic member and that, when pressed against the abutment surface 2, wipes off or scrapes off liquid or solid spread on the abutment surface 2; and a second support member 13 which is supported on the first support member 11 via a leaf spring 14 and to which the base end side of the blade 3 is attached. The leaf spring 14 is attached in such a manner so as to exert a reaction force in response to a friction force causing the second support member 13 to move with respect to the first support member 11 when the blade 3 is pressed against the abutment surface 2 so as to make a sliding movement relative thereto.
