Provided is an insertion-device cleaning implement in which an insertion device attached to a prescribed position of a cleaning-implement main body is held, and a cleaning liquid is directly ejected from different directions on to an area to be cleaned to perform cleaning. In the insertion-device cleaning implement, an axial-direction restriction part which comes into contact with a tip part of the insertion device, and a rotational-direction restriction part which faces an observation surface of the insertion device are provided inside the cylindrical hollow cleaning-implement main body, and are used to position the tip part to attach the insertion device. A plurality of cleaning ports are provided to the inner peripheral surface of the cleaning-implement main body so as to be separated from each other. A raised tip section of a rocking base accommodated in a housing chamber in the tip part comes into contact with a protruded engagement part provided on the inner peripheral surface between the cleaning ports, the positioned state of the tip part is held by the engagement part and the axial-direction restriction part, and the cleaning liquid ejected from the plurality of cleaning ports collides directly with the area to cleaned in the housing chamber to perform cleaning.Linvention concerne un accessoire de nettoyage doté dun dispositif dinsertion dans lequel est maintenu un dispositif dinsertion fixé à une position prédéfinie dun corps principal de laccessoire de nettoyage, et un liquide de nettoyage est éjecté directement à partir de directions différentes sur une zone à nettoyer afin deffectuer le nettoyage. Dans laccessoire de nettoyage doté dun dispositif dinsertion, une partie de restriction de direction axiale qui vient en contact avec une partie de pointe du dispositif dinsertion, et une partie de restriction de direction de rotation qui fait face à une surface dobservation du dispositif dinsertion sont agencées à lintérieur du corps principal creux cylindriq
