Abstract:
1. A structure for mounting a marking plate bearing a marking having directionality such as information, picture, and form on the front surface of a platelike member so that said marking plate can be rotationally adjusted every predetermined angle about a hypothetical axis passing through the thickness direction of said platelike member, wherein: said marking plate has a stem projecting from the back surface of said marking plate, said stem extending through the thickness direction of said platelike member in the condition where the back surface of said marking plate is in contact with the front surface of said platelike member, so that said stem is rotatably supported to said platelike member; the back surface of said marking plate is formed with an engaging portion of said marking plate side for adjusting the rotational angle of said marking plate on said platelike member; the front surface of said platelike member is formed with an engaging portion of said platelike member side adapted to engage with said engaging portion of said marking plate side for determining the rotational angle of said marking plate on the front surface of said platelike member by the engagement with said engaging portion of said marking plate side; a spring member is provided on the back surface of said platelike member and supported to the tip end of said stem so that the downward movement of said spring member from the tip end of said stem in the axial direction of said stem is limited; said spring member has an elastic portion adapted to come into elastic contact with the back surface of said platelike member in the condition where said engaging portion of said marking plate side is engaged with said engaging portion of said platelike member side, thereby maintaining the engagement of said engaging portion of said marking plate side and said engaging portion of said platelike member side owing to the elastic force of said elastic portion to thereby maintain the mounted condition of said marking plate; and when said marking plate is pulled away from the front surface of said platelike member in the mounted condition of said marking plate, said elastic portion is elastically deformed to allow the disengagement of said engaging portion of said marking plate side from said engaging portion of said platelike member side.
