Description

  The present invention relates to an engine generator, and more particularly to an engine generator including an operation panel for controlling the engine and the generator and an output terminal board for outputting electric power from the generator on one side surface of the casing.

  A general engine generator accommodates a generator and an engine that drives the generator, a fuel tank, and the like in a casing provided at an upper portion of a floor base. An operation panel for controlling the generator and an output terminal board having a plurality of connection terminals for outputting the electric power generated by the generator to the outside are arranged. As shown in FIG. 7, as a mounting structure of the operation panel and the output terminal board, a pedestal 53 is installed so as to straddle the generator 52 housed in the casing 51, and the operation panel 54 is disposed on the upper surface of the pedestal 53. , And an output terminal board 55 is fixed to the lower end of the pedestal 53, and an upper cover 56 is detachably provided on the front surface of the operation panel 54. The output terminal board 55 is externally provided below the upper cover 56. There is known a detachable lower cover 57 having an opening to be exposed. (For example, refer to Patent Document 1).

JP 2007-267546 A

  However, in the above-mentioned Patent Document 1, it is possible to easily perform maintenance of the generator 52 positioned below the gantry 53 by removing the lower cover 57. However, the operation panel 54 and the output terminal board 55 are installed in the casing. The wiring work when attaching to and detaching from the 51 is obstructed by the pedestal 53 provided so as to divide the inside of the casing 51 vertically across the generator 52. In particular, the wiring 58 to the output terminal board 55 is laid out. It was possible to work only from below, placing a heavy burden on the workers. In addition, since there are many blind spots due to the gantry 53, workability such as inspection is adversely affected.

  Therefore, an object of the present invention is to provide an engine generator capable of easily and reliably performing wiring work of an operation panel and an output terminal board.

  In order to achieve the above object, an engine generator according to the present invention accommodates a generator and an engine for driving the generator in a casing formed in a box shape, and is operated on a side of the casing on the generator side.
