Plate-like member mounting device

A generally plate shaped member mounting device, comprising:

• a base member;
• a first elastic member;
• and
• a generally plate shaped member having a front surface and a back surface,
• wherein:
• the first elastic member is fixed to an elastic member fixed surface on the back surface of the generally plate shaped member;
• the base member has a base portion and a plurality of supporting portions;
• the base portion has an elastic member abutting surface which the first elastic member abuts;
• the elastic member abutting surface is located between two of the plurality of supporting portions;
• the two supporting portions of the plurality of supporting portions each extend along a first direction which is parallel to the elastic member abutting surface;
• the two supporting portions of the plurality of supporting portions are each located adjacent to the elastic member abutting surface with a distance between each of the two supporting portions and the elastic member abutting surface, respectively, being shorter than a length of the generally plate shaped member along the first direction;
• the two supporting portions of the plurality of supporting portions being configured to support the generally plate shaped member from a front surface side of the generally plate shaped member;
• the first elastic member
• (i) is subjected to first-level deformation in a vertical direction vertical to the elastic member fixed surface in a case where the first elastic member receives a first-level thrust in the vertical direction, (ii) after the first-level deformation, is further subjected to second-level deformation in the vertical direction in a case where the first elastic member receives a second-level thrust in the vertical direction, which second-level thrust is larger than the first-level thrust, (iii) is deformed in the first direction in a case where the first elastic member receives a thrust in the first direction, and (iv) in a case where an edge portion of the generally plate shaped member is inserted between the base member and one of the plurality of supporting portions in the first direction and then the thrust in the first direction is removed, the first elastic member is restored from the deformation in the first direction and abuts the elastic member abutting surface and supports the generally plate shaped member from a back surface side of the generally plate shaped member while the first elastic member is being subjected to the first-level deformation;
• the first elastic member includes (i) a base wall portion which is fixed on the plate like member and (ii) a longitudinal wall portion which is extended from the base wall portion in the vertical direction vertical to the back surface of the generally plate shaped member;
• and
• the first direction is a direction perpendicular to an outer surface of the longitudinal wall portion.
