PROBLEM TO BE SOLVED: To prevent the damages to a stud pin and the drop of a coupling member caused by the contact of a coupling member by fitting the coupling member formed with an opening to be coupled with the stud pin on at least one of elastic supports to a lock section, and providing lugs regulating the fitting position of the coupling member on the elastic support. SOLUTION: An opening 38 of a lock section 36 of at least one elastic support 34 among four elastic supports 34 is set to a size freely coupled with a stud pin, and a coupling member 39 having an opening 38 to be coupled with the stud pin is welded to the opposite face which face the lock section 36 facing a mask frame 31. Two positions on the inside of both side sections near the boundary section between the lock section 36 and a connection section 37 are cut up into a semiconical shape to form lugs 41 for regulating the fitting position of the coupling member 39 to the connecting section 37 side. The fitting position of the coupling member 39 is regulated by the lugs 41, the coupling member 39 is prevented from being fitted protrusively toward the inclined connection section 37, and the deformation and drop of the elastic support 34 can be prevented.
