Abstract
A forceps device includes grasping portions, a support holding the grasping portions, a first rotating shaft that turnably supports the support, a base member that holds the first rotating shaft, first wires that transmit driving forces to move the grasping portions, first guide pulleys arranged coaxially with the first rotating shaft, the first wires running over the first guide pulleys, respectively, and second guide pulleys arranged upstream of the first guide pulleys, the first wires running over the second guide pulleys, respectively. The second guide pulleys are shifted toward one side relative to a position immediately below the first guide pulleys when the first rotating shaft is viewed in front in an axial direction in a state in which a leading end of the grasping portions points upward, and arranged so that a winding angles γ of the first wires respectively around the first guide pulleys are 65° or larger.
