PROBLEM TO BE SOLVED: To provide a shaft tool in a way that a shaft body is formed into one part without any trouble through injection molding of plastic. SOLUTION: This tool is constituted such that a shaft body, a support body 20 provided with a guide part 20 to longitudinally support the shaft body 1 movably along the direction of an axis, and a spring body 3 situated standing in line with the shaft body 1 on the side of the shaft body 1 and exerting an energizing force on the shaft body 1 are integrally provided through injection molding of plastic. The spring body 3 is constituted such that a distance between two ends 30 and 31 of a spring is elastically decreased or increased in the axial direction of the shaft body 1 and spring one end 30 is integrally connected to the shaft body 1 and the other end 31 of the spring is integrally connected to the support body 2. Release parts 24 for molding sized as large as the spring body 3 can be looked in from the outside are formed in a direction approximately orthogonally crossing the axial direction of the shaft body 1 and on both sides between which the spring body 3 is situated.
