A wiper cassette includes a long wiping member which wipes a liquid adhered to a liquid ejecting head which ejects the liquid; a feed roller around which an end of the wiping member is wound in a longitudinal direction; and a winding roller around which other end of the wiping member is wound in the longitudinal direction, and the wiper cassette is mounted so as to be freely detachable and attachable into a wiper holder. Furthermore, the wiper cassette further includes a winding gear supported by the winding roller; and a power point acting portion on which a load acts in a removal direction when the wiper cassette is removed from the wiper holder, in which the power point acting portion is positioned closer to the removal direction side than the winding gear in a mounted state in which the wiper cassette is mounted into the wiper holder.
