Frame body for costume, costume, and method for manufacturing the same

A method for manufacturing a frame for a costume from a sheet-shaped or flat-plate-shaped resin member by deforming the resin member by using a vacuum molding apparatus,

• wherein the method includes:
• a cover mounting step of mounting a sheet-shaped cover on the resin member on which a through hole is formed in advance so as to seal at least the through hole;
• a heating step of heating the resin member and the cover;
• a vacuum molding step of bringing a mold in a predetermined three-dimensional shape into contact with the resin member on which the cover is mounted to vacuum-mold an object in the three-dimensional shape;
• and
• a mold release step of releasing the three-dimensional object from the mold.

A method for manufacturing a frame for a costume by deforming a sheet-shaped resin member by using a vacuum molding apparatus comprising:

• a chamber;
• an elevating table housed in the chamber;
• a pedestal arranged on an upper part of the chamber;
• and
• a heater arranged above the pedestal,
• wherein the method includes:
• a mold installation step of installing a mold in a predetermined three-dimensional shape on the elevating table;
• a resin member mounting step of mounting on the pedestal the sheet-shaped or flat-plate-shaped resin member on which a plurality of through holes are formed in advance;
• a cover mounting step of mounting a sheet-shaped cover on the pedestal so as to seal at least the through hole on the resin member;
• a heating step of heating the resin member and the cover with the heater;
• a vacuum molding step of elevating the mold by using the elevating table to be brought in contact with the resin member and depressurizing the inside of the chamber;
• a mold release step of releasing the molded resin member and the molded cover from the mold;
• and
• the cover detachment step of detaching the cover 40 from the resin member.
