PURPOSE:To facilitate the mounting of an operation display plate by providing a plurality of bores for engagement on the operation display plate and a plurality of protrusions, which are engaged with the bores, on an operation control plate, and by detachably mounting the operation display plate onto the operation control plate by means of the engagement of the protrusions with the bores. CONSTITUTION:A plurality of protruding parts 3 of an operation control plate 1 are first fitted into a plurality of bores 5 of an operation display plate 2, and the operation display plate 2 on which bores 6 are formed is then pushed onto the operation control plate 1 on which protruding parts 4 are formed, so as to fit the protruding parts 4 into the bores 6, thus mounting the operation display plate 2 onto the operation control plate 1. Accordingly, the operation display plate 2 can be mounted without the need for forming a complicated holding structure on the operation control plate 1 or having to use fixing parts such as screws. Further, deformation of the operation display plate 2 is not caused as has been often the case under the conventional mounting methods of inserting an operation display plate into a holding part. Furthermore, the operation display plate 2 may repeatedly be mounted, a clearance between both plates can easily be secured, and a chattering noise or the like can also be prevented from being generated. |
