PROBLEM TO BE SOLVED: To provide a displacement gage for a shape measurement by which a small-diameter hole and a deep hole can be measured and which can be aligned easily with a hole. SOLUTION: The displacement gage is provided with a cylindrical case 31 which is moved along a part to be measured, a holder 33 which is housed at the inside of the case 31, whose central part is borne so as to be rockable, which comprises a gage head 34 at the lower end so as to protrude from the case 31 and so as to be advanced and retreated by coming into contact with the part to be measured and which comprises a horizontal displacement part 35 at the upper end so as to be displaced in the horizontal direction and a measuring part 36 which is installed at the case 31, whose lower end comes into contact with the part 35 so as to be displaced in the vertical direction and which measures its displacement.
