<p>[PROBLEMS] To provide a portable device for exercising straight stroking of the head of a putter club toward a target with right posture and for comprehending the habit of stroke. [MEANS FOR SOLVING PROBLEMS] A pair of contact bodies (18) of string or rod are supported linearly in parallel in the air by a support (14) fixed to a base member (10) at two points of a clamp (16). A detector (22) constituting an attachment (20) fixed closely to the head (8) of a putter club (6) has a U-shaped or L-shaped cross-section. When the head (8) of the putter club (6) is at right position with right posture, the U-shape can keep the pair of contact bodies (18) in noncontact holding state. When the detector (22) detects contact with the contact body (18) during exercise, a warning is given by sound or light. The detector (22) has a plurality of contact sensors (30A, 30B, 30C) arranged at the longitudinal side (24) or the upper or lower side of the U-shaped or L-shaped cross-section, and a different warning is given depending on the contact sensor which detected the contact.</p> |
