PURPOSE:To display the data related to the operation of a vehicle in the front visual field of a helmet and improve the safety of driving by providing a signal processing device for processing and transmitting a data signal and a display device. CONSTITUTION:For the data, the power and signal to a display device 3 are transmitted from a signal processing device 4 through a wiring 5. A plug 6A on the top end of the wiring 5 is connected to a receptacle 6B on the vehicle side. When an occupant wears a helmet 2 and gets on a motorcycle, the plug 6A is connected to the receptacle 6B, and an earth is removed when he gets off the vehicle. When the plug 6A is fitted to the receptacle 6B, a magnet 12 in the plug center part attracts the opposed surface of the receptacle 6B and an iron piece 11 buried therein to connect three wirings. When the plug 6A is pulled by the force more than the attracting force of the magnet 12, the connection is released. Thus, at an abnormality such that the motorcycle 1 is fallen, the plug 6A is released from the receptacle 6B, and the occupant is never exposed to a danger such that the wiring 5 constrains the occupant. |
