Abstract: A steering switch device mounted on a spoke portion of a steering wheel allows a first operating knob which can operate to press an operating surface upward obliquely of the front side to be adjacent to a second operating knob which can operate to tilt an operating surface approximately toward the rear of a vehicle. The first and second operating knobs are arranged such that the operating surface and the operating surface of each other are smoothly continuous due to the presence of a minute gap, and are continuous so as to form a surface following the surface entirely from an upper surface (surface opposing a driver) up to a lateral surface (front side surface when viewed from the driver) of the steering wheel.
