1. A push button structure comprising:
- a stationary structural part having shoulder section; and
an operating member disposed protrudably in the stationary structural part, the operating member having a sliding part configured to slide within the stationary structural part and an operating crown connected on the outside of the sliding part and having an overhang section larger in diameter than the sliding part; and
a cylindrical, elastically deformable flexible member held between the overhang section of the operating crown and the stationary structural part and encircling the sliding part;
wherein said shoulder section has a first surface part facing the sliding direction of the sliding part and a second surface part substantially opposing the sliding part; and
said flexible member includes a cylindrical seal area having an axial-direction protrusion protruding toward said first surface part in a no-load state and a radial-direction protrusion protruding toward said sliding part opposing the second surface part, said cylindrical seal area being fitted into the shoulder part.

Abstract
A push button structure reduces the manufacturing cost as well as thickness by improving the configuration of functional parts of the push button structure. A pipe is fixed in a through-hole of an external case, and the shaft of an operating member is inserted slidably to the pipe. A cylindrical flexible member is held between the pipe and the crown of the operating member.
