A resin-film stretch apparatus comprising:
- a pair of rails;
- a link retainer;
- and
- a link mechanism moveable on the pair of rails to hold a resin film,
- wherein the link mechanism includes:
- a film holder holding a film;
- a first link shaft linked to the film holder;
- a second link shaft linked to the first link shaft;
- a lower link plate linking the first link shaft and the second link shaft;
- an upper link plate linking the first link shaft and the second link shaft;
- a first bracket fixed to the first link shaft;
- a second bracket fixed to the second link shaft;
- a first roller attached to the first bracket and configured to contact with the link retainer;
- and
- a second roller attached to the second bracket and configured to contact with the link retainer,
- wherein the contact of the first and second rollers with the link retainer is configured to suppress lifting of the link mechanism from the pair of rails upon release of the resin film from the film holder.
