Sealing structure

摘要

In a vertical machining center, side covers (22) are provided upright on a saddle on opposite sides of a column. The side covers (22) each have a surface having a fitting groove (22c) defined between an open/close door (22b) and an inspection window (22a) of a rhomboidal shape having anteroposteriorly inclined longitudinal edges. A front cover (25) is attached to the column. Elongate seal members (27) are respectively provided along opposite side edges of the front cover (25) as vertically extending in sliding contact with the surfaces of the side covers (22) for closing small gaps defined between the side edges of the front cover (25) and the surfaces of the side covers (22).
