PROBLEM TO BE SOLVED: To provide an operation unit having a depression operation function, in which an inclination of a push-in movable part toward a push-in direction is suppressed.SOLUTION: The operation unit is so configured that, when a push-in operation is performed at a position of at least surfaces on both sides in a circumferential direction and an inner surface in a radial direction, out of surfaces facing a slide guide 72 in a guide housing part 82, being eccentric relative to a rotational axis in a push-in movable part 70, inclination of the push-in movable part 70 toward a direction parallel to the rotational axis is regulated as a result of the slide guide 72 coming into contact with one of the surfaces. |
