PROBLEM TO BE SOLVED: To provide a push knob structure capable of providing the same operation feeling regardless of a pushing position of an operation part by biasing a hinge part, for sure switch operation. SOLUTION: An operation part 22 is provided of which one end is protruded outside from a body 10 of an electronic apparatus through an opening 10a, and supported retractably. A boss 24 is so extended as to face a switch 34 mounted on a board 30 in the body 10 from one end side of the backside of the operation part 22, following appearing/disappearing of the operation part 22. A first hinge part 26 extends as a pair from both ends of the outer periphery between one end at which the boss 24 of the operation part 22 in the body 10 is formed and the other end, with a free end bent toward the base board 30. The first hinge part 26 extends to the other end which comes away from one end where a plurality of ends bending toward the base board 30 are combined to form the boss 24, and the other end extending in the receding direction is supported in the body 10, so that a second hinge part 28 whose rigidity is lower than that of the first hinge part 26 is provided.
