The invention provides a manipulator, and a manipulator system that has a reduced parts count and a simplified, easy-to-assemble structure yet is capable of smooth actuation. The manipulator (1) is including an operating unit (2b), and a bending assembly (4) that is bent by operation of the operating unit (2b), wherein the bending assembly (4) includes a first link member (11) having a first arc portion (11a), a second link member (12) having a second arc portion (12a), an intermediate link member (13) mounted between the first link member (11) and the second link member (12), a first coupling member (21) that couples the first link member (11) to the intermediate link member (13), a second coupling member (22) that couples the second link member (12) to the intermediate link member (13), and a regulating member (30) that intersects itself between, and is wound around, the first arc portion (11a) of the first link member (11) and the first intermediate arc portion (13b) of the intermediate link member (13) and intersects itself between, and is wound around, the second arc portion (12a) of the second link member (12) and the second intermediate arc portion (13b) of the intermediate link member (13) such that the first arc portion 11a and the first intermediate arc portion (13a) as well as the second arc portion (12a) and the second intermediate arc portion (13b) roll.
