The lever operation block is accommodated and installed in the unit housing. The lever switch is arranged in the unit housing for operating. The lever switch part runs with the rotation of the lever switch on the plane parallel to the housing base and applies the signal of a vehicle. The switch part comprises a switch detent part(320), a switch operation element(330), and a switch fixing unit(340).
