Claims

[Claims for Utility Model Registration] (1) A casing having an upper plate and a lower plate and/or an intermediate plate disposed below the upper plate, and a substantially arc-shaped opening formed in the upper plate. a bending shaft that applies a bending force to a member to be bent by being moved along the opening, a bending roll rotatably supported by the bending shaft, a drive mechanism having a motor, and rotation of the motor. a deceleration mechanism that decelerates the rotation of the transmission gear and transmits the deceleration to the transmission gear of the deceleration output shaft; a driven gear that meshes with the transmission gear and further decelerates the rotation of the transmission gear and transmits the rotation to the bending shaft; When a bending force is applied to the bending member, in a portable bender that has a receiver that supports the bent member and a central axis located at the bending center of the bent part of the bent member, the bending axis is moved after the bending process is completed. The portable bender further comprises a spring supported at one end by the casing and fixed at the other end to the deceleration output shaft to bias the deceleration output shaft to its initial position. . (2) The portable bender according to claim (1), wherein the spring is a composite coil spring in which a torsion coil spring and a tension coil spring are coupled in series via a string member.
