Abstract

PURPOSE:To secure the attachment and to improve the productivity, by providing a protective panel receiver with an opening in the shape of an inverted V- shape at a support frame upper forward end, and providing a protective panel upper forward end with a projection in the shape of an inverted V-shape, so that the inverted V-shaped sections can be engaged with each other. CONSTITUTION:The protective panel receiver 20 is formed with the opening in the shape of an inverted V-shape at the upper forward end of the support frame 2. On the other hand, the forward end of the upper side 4 of the protective panel 4 is formed with the inverted V-shape projection 4d. When this protective panel 4 is attached to the support frame 2, the projection 4d of the upper side 4a of the protective panel 4 is engaged into the receiver 20 of the support frame 2, a lower side 4b of the protective panel 4 is positioned on the outside of the lower side of the protective panel 4, and both the sides are secured by screws 19. In this arrangement, the molding strain in the protective panel 4 is compressed, the upper side 4a is tightly secured to the support frame 2, and therefore the attachment can be secured without requiring the correction of the strain.
