PROBLEM TO BE SOLVED: To provide a simple device for a putting practice which enables a user to fix a line of sight to a golf ball at the time of the address, to set a putter head perpendicular to a direction of the punching out of the ball and to receive an impact at a core of a putter face. SOLUTION: A notch 3 for the punching out of the ball is formed in a tabular member 2 of which the surface is formed to be a specular surface. The golf ball A is placed in the notch section 3 and the address is made. The golf ball A is overlooked almost from above and the positional relation between the own face reflected on the specular surface and the golf ball A is made to be always fixed. A convex member 4 is disposed in the vicinity of a rear end section of the notch 3 to extend perpendicularly to the direction of the punching out of the ball. The putter head B is made to be parallel to the convex member 4. The stroke is made to keep off the putter face C from a side surface (a starting end side of the punching out of the golf ball) of the convex member 4. COPYRIGHT: (C)2007,JPO&INPIT
