Claim:
A golf ball marker formed by die casting, comprising: a pivotal member that includes a plate-shaped hinged portion, a shaft piercing portion formed along one side face of the hinged portion, and a pin-shaped insertion portion formed in a manner so as to stick out downward from a side face of the shaft piercing portion, the pivotal member being pivotable around an axial line of the shaft piercing portion; and a main body that allows the shaft piercing portion to be fitted thereto and the pivotal member to penetrate so as to be shaft-engaged thereto via a shaft extending through the shaft piercing portion and the main body, wherein when the hinged portion is raised upright on a front surface of the main body by the pivotal movement of the pivotal member, the insertion portion is also raised upright on a back surface of the main body cooperatively, when the hinged portion is laid down on the front surface of the main body by the pivotal movement of the pivotal member, the insertion portion is also laid down on the back surface of the main body cooperatively, a housing section for housing the insertion portion is formed on the back surface of the main body, in a state in which the hinged portion and the insertion portion are laid down, the insertion portion is made either substantially flush with the back surface of the main body or housed in the back surface of the main body, wherein a step portion having a shape corresponding to the shape of the hinged portion is formed on the front surface of the main body, and in the state in which the hinged portion and the insertion portion are laid down, the hinged portion is made substantially flush with the surface of the main body, and wherein a magnetic member is embedded in the hinged portion, a suction face is formed in the step portion, a magnet being embedded on the back side of the suction face, and the hinged portion and the insertion portion are allowed to be kept in the laid-down state by having the magnetic member and the magnet attract each other with the suction face interposed therebetween.
