    Abstract: A glass strength evaluation apparatus includes a support unit, a plate disposed on the support unit and including a surface on which a glass article, which is a target to be tested, is disposed, a fixing jig disposed on the plate and a power unit lifting up or down the fixing jig in a vertical direction toward the surface of the plate. The fixing jig includes a body portion, which extends in the vertical direction and lower fixing bolts. A press-fitting member insertion opening is recessed from a bottom of the body portion to extend in an upward direction, lower fixing bolt insertion holes penetrate the body portion, from one side of the body portion, in a first horizontal direction intersecting the vertical direction, to be extended to the press-fitting insertion opening, and lower fixing bolts are coupled into the lower fixing bolt insertion holes.
