1. A neck deflection correction device for a stringed instrument, for correcting deflection of a neck of the stringed instrument, comprising:
a first rod-like member provided in a length direction of the neck;
one end side fixing member attached to one end side of the first rod-like member and another end side fixing member attached to another end side of the first rod-like member opposite to the one end side;
a screw hole formed so as to pass through the another end side fixing member; and
a second rod-like member provided along the first rod-like member, and having a screw shaft part screwed in the screw hole on the another end side, and one end part thereof attached to the one end side fixing member,
wherein the one end side fixing member and the another end side fixing member include fitting grooves fitted on one end part and another end part of the first rod-like member; shaft holes passing through the one end part and the another end part of the first rod-like member from side surfaces of the one end side fixing member and the another end side fixing member; and shaft members inserted in the shaft holes,
the one end side fixing member and the another end side fixing member are fixed to the one end part and the another end part together with the shaft members, and
by screwing between the screw hole and the screw shaft part accompanying rotation of the second rod-like member, the one end side fixing member and the another end side fixing member are pushed in a direction such that the one end side fixing member and the another end side fixing member are drawn to each other or in a direction such that the one end side fixing member and the another end side fixing member are moved away from each other.
