PURPOSE: A ground apparatus of a switch mounted in a steering wheel for a vehicle is provided to prevent wear of the ground apparatus by inserting the ground apparatus to a coupling and rotating integrally with the steering shaft for conducting. CONSTITUTION: A switch is installed in a steering wheel, and connected to a vehicle body through a steering system. A coupling is placed between an intermediate shaft(3) and a gear operating shaft(14), and a conductor(16) is inserted to the coupling for conducting support plates(10,12). The conductor has an elastic part deformed according to an elastic plate(18), and a connecting part combined with the supporting plate. The switch is grounded to the vehicle body through the steering shaft and the gear mechanism by inserting the conductor to the coupling. Noise and wear are prevented with integrally rotating the ground device with the steering shaft.
