Portable engine operated machine
First Claim
1. A portable engine operated machine comprising:
- an engine, a working machine to be driven for operation by the engine, a box-shaped case defining an internal space for holding the engine and the working machine therein and provided with a cooling air passage through which fresh air as cooling air flows into the internal space, and a carrying handle;
wherein the case has, adjacent the carrying handle, a part of an end part thereof depressed inward to form a depressed part lying on an inner side of the handle toward the internal space and defining a recess, the depressed part and the carrying handle define the cooling air passage, and the cooling air passage forms a hand space into which a human hand may be inserted to grip the carrying handle.

Abstract
A portable engine generator, has a box-shaped case defining an internal space for holding an engine and an electric generator to be driven by the engine. The case is provided with carrying handles. The portable engine generator is provided with a cooling air passage through which fresh air as cooling air flows into the internal space while the engine is in operation. An inward depressed part is formed in a front cover of the case on the side of the internal space with respect to the carrying handles The carrying handles and the inward depressed part define the cooling air passage. The cooling air passage serves as a hand space into which human hand is inserted to grip the carrying handles.
