This AC outlet is where AC power can be extracted from the generator by plugging in AC equipment. The output changeover switch is, for example, a DC mode in which the battery is charged by the DC from the generator, an AC mode in which only the AC output is performed,
And DC / AC mode in which these two modes are simultaneously performed.

When the AC output section is composed of an AC outlet and an output change-over switch mounted substantially at the center of the front hanging wall of the seat, charging of the battery and use of various AC devices can be performed immediately. And it can be done easily.

The AC output section has an AC outlet connected to the AC outlet.
It is preferable to include a detecting means for detecting that the device is plugged in, and a control means connected to the detecting means and outputting an AC to the AC outlet based on the detection result. In such a configuration, it is automatically detected that the AC device is plugged into the AC outlet, and the AC outlet is automatically output to the AC outlet, or the generator is stopped. When the AC device is plugged into the AC outlet while the power is on, the generator is automatically activated, and the AC outlet can be automatically output to the AC outlet.

Here, the detecting means is, for example, a light emitting element and a light receiving element which are arranged inside the AC output section and which are turned on from OFF when the plug of the AC device is inserted into the AC outlet to perform the detection. What is A
It is preferable to use a switch which is arranged inside the C output unit and which is formed by a microswitch which is turned off from on when an AC device is plugged in and detects the change.

According to such a device comprising a light emitting element and a light receiving element or a device comprising a microswitch, A
It is possible to reliably detect that the plug of the device C has been inserted into the AC outlet with a simple configuration.
