In-vehicle lever switch device

An in-vehicle lever switch device comprising:

• a cylindrical lever body;
• a first rotating knob and a second rotating knob that are supported so as to be rotatable along an plane orthogonal to an axial direction of the cylindrical lever body;
• and
• a circuit board that is assembled in the cylindrical lever body so as to be oriented along the orthogonal plane,
• wherein a first rotation detection portion, which is used to detect the rotation of the first rotating knob, is provided on one main surface of the circuit board,
• a second rotation detection portion, which is used to detect the rotation of the second rotating knob, is provided on the other main surface of the circuit board,
• the cylindrical lever body comprises a combined pair of halved lever bodies,
• the first and second rotating knobs are rotatably supported by a holder that is assembled in and fixed to the cylindrical lever body,
• the circuit board is mounted on the holder between the first and second rotating knobs,
• the first rotating knob is exposed to the outside at an end of the cylindrical lever body in the axial direction, and
• the second rotating knob is exposed to the outside through window portions formed at the cylindrical lever body.
