An operating device is provided having a supporting member, a button, an elastic member, and a bearing member. The supporting member has an opening which passes through the thickness direction of the supporting member. The button has a shaft and an engaging portion. The shaft is arranged such that the axial direction of the shaft is parallel to the thickness direction of the supporting member. The engaging portion projects parallel to the axial direction of the shaft. The elastic member is set onto the supporting member so as to cover the opening, and has a projecting portion which engages the end of the shaft. The bearing member is provided between the supporting member and the elastic member, which is provided around the opening and is located nearer to the shaft than the engaging portion in the direction orthogonal to the projecting direction of the shaft. The shaft may press the elastic member so that the elastic member is deformed so as to move along the thickness direction of the supporting member in the opening.

1. An operating device comprising: a supporting member that has an opening which passes through a thickness direction of said supporting member;a button that has a shaft and an engaging portion, said shaft being arranged such that an axial direction of the shaft is parallel to the thickness direction of said supporting member, said engaging portion projecting parallel to the axial direction of the shaft;an elastic member that is set onto said supporting member so as to cover the opening, and has a projecting portion which engages an end of the shaft; anda bearing member that is provided between said supporting member and said elastic member, which is provided around the opening and is located nearer to the shaft than the engaging portion in a direction orthogonal to the axial direction of the shaft,wherein the shaft is configured to press said elastic member so that said elastic member is deformed so as to move along the thickness direction of said supporting member in the opening. 2. The operating device according to claim 1 further comprising a push switch that faces the end of the shaft, wherein the shaft covered by the projecting portion projects from an inner side of the opening, and pushes said push switch, when said button is pushed. 3. The operating device according to claim 1, wherein the engaging portion has a corner which contacts said elastic member, and said corner is chamfered. 4. The operating device according to claim 1, wherein said bearing member is provided in said elastic member. 5. The operating device according to claim 4, wherein said bearing member has a corner which contacts said supporting member, and said corner is chamfered. 6. The operating device according to claim 1, wherein said bearing member is provided in said supporting member. 7. The operating device according to claim 6, wherein said bearing member has a corner which contacts said elastic member, and said corner is chamfered. 8. The operating device according to claim 1, wherein said button comprises a fulcrum portion which projects parallel to the axial direction of the shaft, said elastic member comprises a projecting fulcrum portion which covers the fulcrum portion, said the projecting fulcrum portion contacts said supporting member, said button pivotally engages the projecting fulcrum portion, the engaging portion being provided in proximity of pivoting ends of the button, and the shaft is nearer to the fulcrum portion than the engaging portion in the direction orthogonal to the axial direction of the shaft. 9. The operating device according to the claim 1, wherein said button comprises: a first button member that has a pushed portion which is generally cylindrical, engaging portions which project from the pushed portion in parallel to the axial direction of the pushed portion, and a projecting portion which projects in the radial direction of the pushed portion from the engaging portion; anda second button member that is generally cylindrical, has shafts which project in the axial direction of the second button member and an inner surface which freely fits a lateral surface of the pushed portion,wherein an end of the inner surface engages the projecting portion. 10. The operating device according to claim 9, wherein said elastic member, said supporting member, and said bearing member form an air chamber, and the air chamber is configured to be crushed by a pushing of said engaging portion. 11. A waterproof operating device comprising: a button that has a shaft;a supporting member that has an opening which passes through a thickness direction of the supporting member;an elastic member that is set onto said supporting member so as to cover the opening, and has a projecting portion which engages an end of the shaft;a first rib that is provided around the opening between said supporting member and said elastic member; anda second rib that is provided around said first rib between said supporting member and said elastic member, said first rib and said second rib forming a chamber between them, the chamber being provided around the opening, and a cross-sectional area of the chamber being larger than a cross-sectional area of the opening in a direction orthogonal to a projecting direction of the shaft,wherein the shaft is configured to press said elastic member so that said elastic member is deformed so as to move along the thickness direction of said supporting member in the opening. 12. The waterproof operating device according to claim 11 further comprising a push switch that faces the shaft, wherein the shaft projects from the opening, and pushes said push switch when said button is pushed. 13. The waterproof operating device according to the claim 11, wherein said first rib is provided in said elastic member. 14. The waterproof operating device according to the claim 11, wherein said second rib is provided in said elastic member. 15. The waterproof operating device according to the claim 11, wherein said first rib is provided in said supporting member. 16. The waterproof operating device according to the claim 11, wherein said second rib is provided in said supporting member. 17. The waterproof operating device according to claim 11, wherein said first rib, said second rib, and said elastic member form an air chamber, and the air chamber is configured to be crushed by a pressure from outside of the waterproof operating device.
