[Detailed description of the device]

[0001]

[Industrial application] The present invention is an attachment for detachably attaching maintenance equipment (maintenance tools, spark plugs, etc.) equipped to an engine generator (small generator combined with a general-purpose engine). It is about structure.

[0002]

2. Description of the Related Art Among maintenance equipment, a tool for exchanging a spark plug is special, so that it is usually equipped in an engine generator.

[0003] Conventionally, this type of tool is often attached alone or together with other maintenance tools in a tool bag when the engine generator is shipped. But,
The use of a tool bag is inconvenient because it is necessary to carry the tool bag with the engine generator, and the cost of manufacturing the tool bag is required, and the space for storing the tool bag during transportation increases and the load is bulky. Therefore, there is an inconvenience that transportation costs increase.

Therefore, there has been proposed a structure in which an engine generator main body is provided with a storage box or a support portion for maintenance equipment and the maintenance equipment is equipped.
For example, Japanese Utility Model Publication No. 62-28561 and Japanese Utility Model Publication No. 63-
The example described in Japanese Patent No. 20834 is an example thereof. The former is provided with an openable and closable cover at a predetermined position of the main body, and a tool box and a spark plug mounting portion are provided therein. In the latter type, a spark plug hole is provided in a fuel tank installed on the cylinder head, and a support for spark plug replacement equipment is provided on the back surface of a lid that opens and closes the hole.

[0005]

However, the former of the above publications requires a separate storage box for tools and spark plugs and an openable / closable cover, which complicates the structure and reduces the number of parts. Increase, and manufacturing cost increases. Further, the latter is premised on the fact that the fuel tank is provided with a spark plug hole, and therefore cannot be carried out by an engine generator having no such hole. Therefore, it is usually necessary to carry the above-mentioned tool bag.

The present invention has been made in view of the above points,
It is possible to attach maintenance equipment to the engine generator, which makes it possible, for example, to quickly and easily perform work such as inspection, cleaning, and replacement of spark plugs, and also to reduce the number of parts and cost. It is an object of the present invention to provide an attachment structure for maintenance equipment having an advantage.

[0007]

In order to achieve the above object, the installation structure of the maintenance equipment of the present invention is a space where a hand can be inserted from the opening of at least one side of the engine generator to the back surface of the control box. In addition, the control box is made of synthetic resin, and an elastic pinch made of synthetic resin for detachably attaching maintenance equipment is integrally provided on the back surface of the control box.

[0008]

According to the maintenance equipment mounting structure of the present invention having the above-described structure, the maintenance equipment, for example, the plug wrench and the plug wrench turning rod are mounted between the elastic holding portions on the back surface of the control box. When inspecting or cleaning the spark plug, the plug wrench and the plug wrench turning rod can be taken out by inserting a hand into the engine generator through the (one side) opening. Then, the spark plug can be removed by fitting the plug wrench into the spark plug arranged in the cylinder head of the engine, and rotating the plug wrench with the rod to loosen it. After inspection and cleaning, the spark plug can be attached to a predetermined position of the cylinder head in the reverse order. Also, the plug wrench and its turning rod may be attached between the elastic holding portions on the back surface of the control box in the reverse order of the above.

In addition, in the attachment structure of the maintenance equipment of the present invention, the elastic holding portion projecting on the back surface of the control box is integrally formed at the same time when the control box is formed, so that the number of parts does not increase. Moreover, since the equipment for maintenance can be attached to the back of the control box at a cover position, the appearance is good and rain and wind do not directly hit the equipment,
In addition to being well protected, there is no need to increase the external dimensions of the engine generator because it requires only a small space for installing equipment.
