<p>A golf ball marker is used for marking a golf ball hit onto a putting green and includes a circular base disk and a pin-like embedded portion extending from the base disk and insertable into the green. A standing portion is hingedly mounted on one end of the base disk so as to be rotatable. The standing portion and the base disk engage each other when an engaging protrusion engages an engaged hole. When the marker is far away from a cup on the green, the engagement of the engaging protrusion and the engaged hole is released and the standing portion is raised up. The base disk becomes substantially planar with the putting green, the standing portion is capable of standing at an upper side of the base disk, and the embedded portion extends down from a backside of the base disk so as to be embedded into the green.</p> |
