る樹脂コーテイング用マスキング治具。[Claims for Utility Model Registration] Masking treatment for preventing resin powder from being fused to the inner peripheral surface of the through hole and around the opening when coating the outer surface of a target member having a through hole with resin powder by fusion. a first mask member and a second mask member each having a through hole in the center and capable of being closely attached to both end surfaces of the target member where the through hole opens; and a first mask member and a second mask member that are inserted into the through holes of both of the mask members. a first large-diameter portion and a second large-diameter portion provided at both ends of the rod protruding from the first mask member and second mask member, respectively, and at least one of which is separate from the rod; and a cylindrical shape extending from the periphery of the through hole of the first mask member in a direction parallel to the center line of the through hole, and fitted to the first large diameter portion in a slidable and non-rotatable manner in the axial direction. a member, disposed inside the cylindrical member between the cylindrical member or the first mask member, and the first large diameter portion, the first large diameter portion and the first mask member being mutually connected; a spring member that biases the rod in a direction away from the rod; and a separate large diameter portion that is a large diameter portion of the first diameter portion and the second large diameter portion that is separate from the rod, respectively By engaging with each other, the relative rotational motion between the separate large-diameter portion and the rod is converted into movement of the separate large-diameter portion toward and away from the other large-diameter portion, and by separating from each other. a first engaging portion and a second engaging portion that enable separation of the separate large diameter portion from the rod and removal of at least one of the first mask member and the second mask member from the rod; In the attached state of the target member, the elastic force of the spring member causes the second large diameter portion to move around the through hole of the second mask member, and
A masking jig for resin coating in which the first mask member and the second mask member are each brought into close contact with the periphery of the through hole of the target member.
