PROBLEM TO BE SOLVED: To provide a mold fixture, in which mortar filled to a cone section after mold release is not dripped and is not dripped after peeling, in the inner- mold fixture used for a main-girder bottom-force surface of a bridge or the like. SOLUTION: In the inner-mold fixture used for the main-girder bottom-force surface of the bridge or the like, the inner-mold fixture is composed of a truncated cone-shaped cone, an inverse cone, in which the outer circumferential surface of the cone is covered with a truncated cone shape at an inverse grade, and a cut surface, on which the inverse cone is installed along the height direction. In the inner-mold fixture used for the main-girder bottom-force surface or the like of the bridge, the inner-mold fixture is constituted of the truncated cone- shaped cone, the inverse cone, in which the outer circumferential surface of the cone is covered with the truncated cone shape at the inverse grade, and a section, in which a trapezoidal-shaped sectional cut surface is formed so that inner width is widened along the height direction in the inverse cone.
