PROBLEM TO BE SOLVED: To provide a part fixture that prevents a come-off block pin from breaking, allowing easy exchange of parts such as metal lath. SOLUTION: A mounting base 16 is formed on an outer frame 13 and an inner frame 14 of a grille frame 12 integrally. A plurality of locking pieces 18b of a locking fitting 18 are engaged with a locking hole 16a of the mounting base 16 by elastically deforming and reducing the diameter of the locking pieces 18b. A locking projection 19b of a come-off block pin 19 is inserted into a center hold 18d of the locking fitting 18b, the locking projection 19b is locked at the end portion of each locking piece 18b to prevent the diameter of each of the locking piece 18b from narrowing. A screw portion 19c of the come-off block pin 19 is passed through a mesh 15b of a metal lath 15 and a nut 20 having a screw hole 20c is screwed together with the screw portion 19c. The metal lath 15 is sandwiched and held between a flange 18a of the locking fitting 18 and a flange 20a of the nut 20.
