1. A preform shaping apparatus comprising:
at least one mold for placing and shaping a laminated body of fiber sheets which is a material of a fiber reinforced plastic; and
at least one pin that prevents the fiber sheets from being misaligned by stinging the laminated body of the fiber sheets with the at least one pin,
wherein the at least one mold includes:
a first mold; and
a second mold opposite to the first mold,
wherein the at least one pin is projected from a first surface of the first mold toward the second mold,
wherein the second mold includes:
a second surface; and
a clearance adjacent to and penetrating into the second surface, the clearance being a hole or a groove that penetrates into the second mold having an opening surrounded by the second surface, and
wherein the at least one pin is configured, in a state where the surface of the second mold is in contact with a surface of the laminated body of the fiber sheets, to be inside the clearance in order to avoid interference with the second mold.
