Vibration welding device, vibration welding method, vibration welding mold, and vibration welding molded article

A vibration welding device, comprising:

• a vibration welding mold that is configured including an upper mold and a lower mold divided in an up-down direction, the upper mold being fitted with a first component and the lower mold being fitted with a second component, the first and second components each forming an elongated shape having a bent portion, and the vibration welding mold being disposed with length directions of the first component and the second component along a left-right direction;
• a plurality of first mold divisions that configure one of the upper mold and the lower mold, and that are divided in the left-right direction;
• a pressing device that is coupled to each of the plurality of first mold divisions, and that applies pressure to the first mold divisions in a state in which the upper mold is closed against the lower mold;
• and
• a vibration device that is distinct from the upper and lower molds, that is coupled to each of the plurality of first mold divisions, and that vibrates the first mold divisions in the state in which the upper mold is closed against the lower mold.
