Claims

[Scope of utility model registration request]

A guide groove with a V-shaped cross section is formed vertically on the back side. It is supported by the arm base and the lower side of the pipe holder. When the arm rises, the tip is guided by the side wall of the guide groove, allowing for centering without tracking errors when the arm finishes rising. A guide element that sets the arm in the state position, and a coil spring biasing force that is attached to the arm base so that it can slide in the vertical direction and penetrates the pipe holder with play, so that when the arm is raised, the guide element is downward, and when the arm is lowered, the coil spring is biased upward. a lift shaft that is moved through the lift shaft, a lid piece that is rotatably supported on the head side of the lift shaft and retracts above the pipe holder when the arm is finished rising, and a lid shaft that is provided on the arm base side and inside the arm base. It includes a rotation prevention ball that is pressed into a V-shaped cross-sectional groove formed in the vertical direction on the side surface, and a rotary protrusion that fits into the lower surface of the pipe holder upper surface and the lower surface of the lid piece when the arm is lowered. V-shaped grooves are formed respectively, and the lifter pieces are rotatably supported on the lift shaft by ball bearings, and there is a space between the lift shaft and the lid piece to cancel the natural horizontal rotational force of the arm when the arm is lowered. A linear tracking arm is characterized in that a leaf spring is interposed between the two to obtain the necessary frictional force between the two.
