Mounting device

1. A mounting device comprising:

a base that is annular and has an elastic body;

first mounting arms that have elastic bodies and extend from said base in the outward radial direction of said base;

second mounting arms that have elastic bodies and extend from said base in the outward radial direction of said base;

first engaging portions that project orthogonally to the axis of said base from the edge of said first mounting arms; and

second engaging portions that project in the direction opposite to the projection direction of said first engaging portions, from the edge of said second mounting arms;

said first engaging portions projecting parallel to each other in the same direction.

2. The mounting device according to claim 1 , wherein said first mounting arms comprise first holes that pass through each of said first mounting arms in a direction orthogonal to the extension direction of said first mounting arms, and said second mounting arms comprise second holes that pass through each of said second mounting arms in a direction orthogonal to the extension direction of said second mounting arms.

3. The mounting device according to claim 1 , wherein said base comprises a third hole that is cylindrical and passes through said base, and the central axis of said third hole is coaxial with the central axis of said base.

4. The mounting device according to claim 1 , wherein each of said first mounting arms comprises a first absorber that projects parallel to the projection direction of said first engaging portion, each of said second mounting arms comprises a second absorber that projects parallel to the projection direction of said first engaging portion, and said base comprises a third absorber that projects parallel to the projection direction of said first engaging portion.

5. The mounting device according to claim 4 , wherein said first, second, and third absorbers are provided on concentric circles around the axis of said base, and are evenly spaced in the radial direction of said base, and the lengths of said first, second and third absorbers along the axis of said base being equal.

6. The mounting device according to claim 1 , wherein said first engaging portion comprises an elbow portion that is made by connecting two rectangular plates which project in the direction orthogonal to the projection direction of said first mounting arm, and a cover plate that hangs across the first and second sides which are the edges of said elbow portions in their projection direction, and the internal angle formed by said plates faces said base.

7. The mounting device according to claim 6 , wherein the bisector of said inner angle intersects the axis of said base.

8. The mounting device according to claim 1 , wherein said second engaging portion comprises a fitting portion that projects from the edge of said second mounting arm and a stopping portion that is provided on the edge of said fitting portion, and the projected area of said stopping portion which projects toward the orthogonal surface of the projection direction of said engaging portion being larger than that of said fitting portion.

9. The mounting device according to claim 1 , wherein said first engaging portions may hold corners of a liquid crystal panel.

10. A digital camera comprising:

said mounting device described in claim 1 ;

an exterior member that is provided on an exterior of said digital camera; and

inner members that is provided in said digital camera;

said mounting device being provided between said exterior member and the inner members.
