ー。 A main arm that is slidably and fixedly supported on a column installed on the base, a pair of sub-arms that are rotatably supported at the tip of the main arm, and a slider that is attached to each tip of the pair of sub-arms. In a dental model surveyor equipped with a vertical measuring rod and a horizontal drawing rod that are movably and fixedly supported, the vertical measuring rod and the horizontal writing rod are respectively fitted to the tips of a pair of sub-arms, and each sub-arm The vertical measuring rod and horizontal drawing rod are slidably fitted into the threaded pipes protruding downward, respectively, and the cap nuts loosely fitted into the vertical measuring rod and the horizontal drawing rod, respectively, are screwed into the screw pipes. Insert the split rings made of synthetic resin loosely fitted into the marking rods into the gaps provided between the vertical measuring rod and the threaded pipe, and into the gaps provided between the horizontal marking rod and the threaded pipe, respectively. The vertical measuring rod and the horizontal drawing rod are fixed to each sub-arm by press-fitting, respectively.
A dental model surveyor characterized in that each of the bases of the pair of sub-arms is formed with an arcuate surface to be brought into contact in order to regulate the minimum angle between the pair of sub-arms.
