一層容易に行うことができる。In this embodiment, an operator holds an internal combustion engine for driving a saw chain, a fuel tank,
This is an example in which the present invention is applied to a fuel tank of a chain saw having a well-known configuration, which accommodates an oil-lubricating oil tank, a carburetor, etc., and has a front handle and a rear handle (not shown), and a body held by an operator with both hands 1, a fuel tank 2 is disposed below the fuel tank 2, and the fuel tank 2 is covered and protected by a casing 3 of the main body 1. The fuel tank 2 is formed of a relatively thin plastic material, is translucent, allows the contents to be seen through from the outside, and stores the fuel 5 to be supplied to the internal combustion engine 4 therein. The fuel tank 2 is integrally formed on one side thereof with a cylindrical transparent projecting portion 6 projecting outward from the casing 6. The transparent projecting portion 6 is used by an operator who holds the main body 1 while working. For example, it is exposed by being projected to the outside by, for example, about several millimeters from the opening 7 formed in the side portion of the casing 3 which is easily visible in a natural view. The transparent projecting portion 6 is integrally formed with a fuel inlet 8 for injecting fuel into the fuel tank on the exposed outer surface thereof. A screw 9 is formed on the outer peripheral surface of the fuel injection port 8, and a cap 10 is detachably screwed to the screw 9. The outer diameter of the cap 10 is the fuel tank 2
Is slightly smaller than the outer diameter of the see-through overhanging portion 6 of FIG. An externally exposed annular exposed portion 11 is formed that allows a person to naturally view the field during work. Since the fuel in the fuel tank 2 naturally exists also inside the transparent projecting portion 6, the liquid surface 12 of the fuel 5 appears at the annular exposed portion 11 and the operator can change the position of this liquid surface. It is possible to easily check the amount of the fuel 5 in the fuel tank 2 by visually observing the cap 10 from any side around the cap 10 that naturally comes into view. If the outer peripheral portion 13 of the cap 10 has a scale line 14, the liquid surface 12 can be visually checked and the liquid amount can be checked more easily.
考案の効果 以上説明した本考案の構成により、本考案は従来に比べ
てタンクの可透視張り出し部分をケーシングから外部へ
突出するという簡単確実な構造により、作業者が本考案
に係る携帯形作業機で作業中にも作業機のタンク内の内

ンソーでは燃料切れが作業の途中でなくなったりする不
都合が解消される等の効果を奏する。Advantageous Effects of Invention With the configuration of the present invention described above, the present invention has a simple and reliable structure in which the transparent projecting portion of the tank is projected from the casing to the outside as compared with the conventional one, so that the worker can carry the portable work machine according to the present invention. Therefore, it is possible to perform the work while checking the amount of the contents in the tank of the working machine even during the work. For example, with a chain saw, the inconvenience of running out of fuel during the work is eliminated.
