DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for storing articles such as tools of a general-purpose engine used as a power source of a portable generator or the like.

[0002]

2. Description of the Related Art In a general-purpose engine used as a power source for various portable power sources and generators, when an engine malfunctions, a plug wrench, a screwdriver, or the like is used to attach and remove a spark plug for inspection. Tools are required. Usually, such a tool is stored in a predetermined tool bag or the like so as to be portable and portable.

[0003] In addition, there is an accessory cleaner provided on one side of an air cleaner of a general-purpose engine for accommodating tools and the like (see, for example, JP-A-1997-317487).

[0004]

A portable tool stored in a tool bag is not always carried around when a general-purpose engine is used. For this reason, there is an inconvenience such as noticing that the user does not have the portable tool when the engine is malfunctioning and returning to finding out. Further, since the general-purpose engine and the tool bag are separate from each other, it is often inconvenient to forget the place where the tool is placed or to obstruct the tool bag when carrying the engine.

It is also conceivable that tools are stored in the accessory storage chamber in the air cleaner box so as to avoid forgetting to put the tools or forget to carry them. However, the air cleaner needs a predetermined volume in order to reduce air resistance and allow air to be taken in efficiently, and the provision of a tool box increases the volume accordingly, causing a problem that the air cleaner becomes large. .

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and has a fan cover provided on a side surface of an engine crankcase and an air guide provided with a swelling portion to remove articles such as tools. It is an object of the present invention to provide an article storage structure of a general-purpose engine that is capable of storing articles, is convenient for taking articles in and out, and can always use articles such as tools.

[0007]

The present invention has the following configuration to solve the above-mentioned problems. That is, the present invention provides a general-purpose engine in which an engine air cooling fan cover and an air guide are provided on one side surface of a crankcase in the crankshaft direction, and the fan cover and the airguide project outward from the outer periphery of the crankcase when viewed in the crankshaft direction. An article storage structure for a general-purpose engine, wherein a swelling portion is formed, and a storage portion for inserting and housing an article such as a tool is provided in the swelling portion. Preferably, the engine cylinder is inclined, and the bulging portion is located below the engine cylinder when viewed in the crankshaft direction. Further, it is preferable that an insertion hole in which an elastic grommet is attached to an air guide is formed in the bulging portion, and an article receiver is formed in the fan cover.

According to the present invention, in a general-purpose engine,
The fan cover on the side of the crankcase and the swelling part provided in the air guide have a storage part that inserts and stores articles such as tools, so that the tools are always with the general-purpose engine, and when the engine malfunctions The tool can be used immediately for such purposes, and the user does not forget to bring or leave the tool. The swelling portion is provided by using the space portion below the cylinder of the inclined engine, and the swelling portion is located below the engine cylinder in the crankshaft direction, so that the empty space below the cylinder is utilized. Tools can be stored and tools can be easily taken in and out.
The overall size of the engine does not increase.

Further, by inserting an article such as a tool into the grommet of the air guide and receiving it by the tool receiver of the fan cover, vibration of the article can be prevented during operation of the engine, and the article does not fall off. Then, necessary tools can be taken out, which is convenient for use.
