Claims

[Scope of utility model registration request]

(1) A base body placed on a reference surface, a straightedge set up from the base body, and a reference plane centered on the fulcrum of the base body when the straightedge is in contact with a vertical surface on the reference surface. A squareness measuring instrument comprising: a tilting drive mechanism provided on the base at a position spaced a predetermined distance from the fulcrum to detect tilting.

(2) Utility model registration In claim 1, the tilt detection mechanism is a dial gauge that is attached to the base so that the measuring point contacts the reference surface and the moving direction of the measuring point is in the vertical direction. A squareness measuring instrument characterized by: −

(3) Utility model registration Claims 1 or 2, wherein the base body is provided with a spindle whose tip abuts the reference surface and whose axis extends in the vertical direction, and which is moved forward and backward by a screw feeding method. 1. A squareness measuring instrument comprising a tilting drive mechanism for tilting the base body relative to a reference plane according to the amount of advance and retreat of the spindle.
