Abstract: A foldable mechanism and a foldable terminal. The foldable terminal includes the foldable mechanism. The foldable mechanism is conducive to a lightweight design of the foldable terminal. The foldable mechanism includes a base and a pressing plate assembly. The pressing plate assembly is mounted on the base. The pressing plate assembly includes a first pressing plate and a first pressing plate swing arm. The first pressing plate is an integrally formed structural member. A sliding portion of the first pressing plate swing arm is slidably connected to the first pressing plate, to implement slidable connection between the first pressing plate swing arm and the first pressing plate. A rotating portion of the first pressing plate swing arm is rotatably connected to the base, to implement rotatable connection between the first pressing plate swing arm and the base.
