Each of pressure-detecting switches to be connected to one another has a first connector provided at one side section and a first connector provided at the other side section. Electric wiring is mutually effected for the pressure-detecting switches by attaching/detaching the first connectors. The pressure-detecting switches are mutually fixed by using a fixing mechanism arranged for the side sections to effect the function for mutually attaching/detaching the pressure-detecting switches.
