Claims (1)

[Claims for Utility Model Registration] An elongated base body disposed on the outer circumferential side of a rotating operation part of a handle provided at a fixed radial position with respect to the rotation center, and extending in a radial direction with respect to the rotation center of the handle; , a mounting head provided at the end of the base on the handle side and attached to the rotating operation part of the handle; and a mounting head provided on the other end of the base relative to the mounting head;
A handle tightening tool comprising: a grip section that receives manual torque applied in the rotational tightening direction of the handle and transmits the tightening force from the mounting head to the rotating operation section of the handle; A first attachment part that can be attached to the rotation operation part of the right tightening handle in a normal rotation state with the axis as the base, and a second attachment part that can be attached to the rotation operation part of the left tightening handle in an inverted state with the longitudinal direction as the base axis. a first base body having a mounting head at its distal end and having side face parts on both sides in the longitudinal direction of the base body; a second base body having a gripping part at its base end and having side face parts on both sides in the longitudinal direction of the base body; , one side surface on the tip side of the second base, and the first
When one side surface portion on the proximal end side of the base body is overlapped with each other while facing each other, and when manual torque is applied to the gripping portion of the second base body in the tightening direction of the handle, the overlapped side portions The distal end portion of the second base body and the proximal end portion of the first base body are connected so that they are close to each other, and the first base body and the second base body are connected close to each other.
A pressure sensor is disposed on the opposite side surface of either one of the overlapping parts of the base body, and the contact pressure between the pressure sensor and the opposite side face of the base body is transmitted to the handle from one of the attachment parts of the mounting head. A handle tightening tool comprising: a tightening torque detection section that detects tightening force.
