<p>A measuring head capable of easily setting a zero-point and the amount of a front travel, wherein first the amount of the front travel is set by merely allowing contacts (34, 34) to abut on a master (50), levers (42) are set to closed positions by rotating in the directions of arrows (E) to fix bearing members (36) to swing pivot shafts (28), and measuring levers (32) are deflected from a position where the amount of the front travel is set to the zero-point position since the measuring levers (32) are deflected by an amount equivalent to the amount of the front travel by the restoring force of the bearing members (36) transmitted from the bearing members (36) to the measuring levers (32) through arms (38), cam plates (40), and shafts (48), namely by a reaction force, whereby the zero-point position can be set automatically.</p> |
