の出費を余儀なくされる等の欠点を有している。(2) A type has been proposed in which a fuel tank is fixed between the operating handle and the engine via an elastic material in the outer tube. (See Japanese Utility Model Publication No. 56-54752 as an example.) Furthermore, there is also a type in which a fuel tank is provided between the operating handle and the muffler, and the engine is suspended and fixed to the outer pipe in front of the operating handle via a mounting bracket. Proposed. (For example, see Japanese Patent Application Publication No. 17444/1983.) [Problem to be solved by the invention] In the case of (1) mentioned in the section of the prior art,
(a) Vibrations and heat generated when the engine 2 is driven are directly transmitted to the fuel tank 1, and the fuel tank 1 is transferred to the engine 2.
There is a risk that the fastening device (not shown) that is fastened to the blade will gradually loosen, or the fuel tank 1 will overheat, causing the fuel to vaporize. , the work must be interrupted and the worker must turn to the engine 2 side, (c)
Supplying fuel is a little difficult because it is close to the ground, and (d) Furthermore, when the brush cutter is placed on the ground when starting the engine 2, there is a risk that the fuel tank 1 will be directly exposed to the ground and cracked or damaged due to friction. There is a risk of wear due to contact with the ground due to the generation of vibrations, especially after the engine 2 is started, so if a protective material is attached to the fuel tank 1 to prevent it from coming into direct contact with the ground. There is also. However, installing such protective materials increases the weight of the brush cutter as a whole, and requires labor and extra materials for installation, which has disadvantages such as forcing the user to spend extra money. ing.
（）の場合にあつては、弾性材を介し外管に

れ、稍々もすれば燃料が受皿の外に流出する惧れ
もあり、また、残存量確認に際し、作業を中断
し、作業者はエンジン側にふりむかなければなら
ない等の欠点を有している。 In the case of (), since the fuel tank is fixed to the outer tube through an elastic material, vibrations caused by the engine driving and shocks caused by contact with foreign objects during brush cutting are transmitted to the outer tube. For this reason, when the fuel tank cracks or is damaged, it is extremely troublesome to attach and detach it from the outer pipe of the fuel tank itself when replacing it, and if fuel remains, it may cause the entire brush cutter to topple over when it flows out from the oil filler port. Otherwise, the operator may be forced to lean over, and there is a risk that fuel may leak out of the saucer.Furthermore, there are drawbacks such as the operator having to stop work and turn around to the engine side when checking the remaining amount. have.

招来すると共に、（）の場合におけると同様に
燃料の残存量確認に際し、燃料槽側にふりむかな
ければならない等の欠点を有している。 In the case of (), the fuel tank is suspended and fixed to the outer tube provided with the engine in front of the operating handle, so the center of gravity is on the mower blade side, and the work of hanging and supporting the mower is difficult. During grass cutting work, workers have difficulty maintaining overall balance, which leads to early fatigue of the workers, and, as in case (), they have to turn to the fuel tank side when checking the remaining amount of fuel. It has disadvantages such as:

するものである。 This idea was proposed by focusing on the above-mentioned drawbacks, and its purpose was to attach the fuel tank to the outer tube in a detachable manner so that the fuel tank could be easily and quickly removed or installed as needed. To provide a fuel tank mounting device for an engine for a brush cutter, which allows the user to easily check the remaining amount of fuel at any time even during work, and maintains the balance of the brush cutter as a whole well.

Since this idea has the above-mentioned configuration, the first
In the embodiment, a worker (not shown) hangs the shoulder band b3 on his shoulder, grasps the operating handle 9,
When the engine E is started, the cutting blade 7 is rotated by the rotation of the transmission shaft 5 through a group of gears in the gear housing 6, and a desired brush cutting operation is performed. Since the fuel tank T3 is set above the outer pipe 8 via the mounting bracket M3 , vibrations, heat, etc. generated by the driving of the engine E are not directly transmitted to the fuel tank T3 . There is no risk of the T 3 shaking, vibrating or overheating, and it is installed in the fuel tank.
The amount of fuel remaining in T 3 can be easily checked, allowing work to be carried out with peace of mind.Furthermore, the fuel tank T 3 is interposed between the engine E set at the rear end of the outer tube 8 and the operating handle 9. As a result, the balance of the brush cutter as a whole can be well maintained, the operator does not get fatigued early, and it is easy to work. Even when placed on the ground, the bottom surface of the fuel tank T 3 does not touch the ground, so there is no risk of cracks, damage, contamination, etc. due to unexpected contact with foreign objects, and fuel supply is easy. Since the fuel tank T 3 can be easily attached and detached from the outer pipe 8, the fuel tank T 3 can be easily replaced and inspected, making its handling convenient.
Furthermore, the connecting piece 1 of the shoulder band b 3 is placed near the fuel tank T 3 .
0 can be attached and detached freely, so workers can continue working in a comfortable posture at all times by changing or selecting a shoulder strap of the appropriate length according to their own physique and the conditions of the work area. It is possible.
また、第２実施例にあつては、燃料槽T4上方
に肩掛バンドb4が係脱自在に臨ませてあるので、
第１実施例におけると同様に燃料槽T4内の燃料
残存量の確認が容易であり、また、第１実施例に
比し燃料槽T4の外管８に対しより安定下に保持
可能にして作業者はさらに安楽な姿勢で作業に従
事できる。 In addition, in the second embodiment, since the shoulder band b 4 faces above the fuel tank T 4 in a detachable manner,
As in the first embodiment, it is easy to check the amount of fuel remaining in the fuel tank T4 , and compared to the first embodiment, the fuel tank T4 can be held more stably in the outer pipe 8. This allows the worker to work in a more comfortable posture.
