Abstract

A fuel tank comprises a circular column-shaped fuel tank body, a handle, and a first connector. The circular column-shaped fuel tank body is provided so as to be detachably attachable to a fuel-powered device. The handle is formed on one end side in a length direction of the fuel tank body. The first connector is formed on another end side in the length direction of the fuel tank body and configured such that, by installing the fuel tank body to the fuel-powered device, the first connector is connected to a second connector provided at the fuel-powered device so as to enable fuel to be supplied to the fuel-powered device.

First claim

What is claimed is:

1. A fuel tank comprising:
a cylindrical fuel tank body provided so as to be detachably attachable to a fuel-powered device, the fuel tank body having one end side and another end side, the one end side and the another end side being in a length direction of the fuel tank body;
a recess at the one end side of the fuel tank body;
a handle formed on the one end side of the fuel tank body, the handle disposed in the recess;
a first connector formed on the another end side of the fuel tank body and configured such that, by installing the fuel tank body to the fuel-powered device, the first connector is connected to a second connector provided at the fuel-powered device so as to enable fuel to be supplied to the fuel-powered device; and
a cover member detachably attached to the fuel tank body, the cover member defining the recess, the cover member includes fitting holes, the handle includes claw portions that project out from outer peripheral faces of pillars of the handle, and the claw portions are received in the fitting holes.

2. The fuel tank of claim 1 , wherein an end face on the another end side of the fuel tank body is formed in a flat shape.

3. The fuel tank of claim 1 , wherein:
a recess indented in the length direction of the fuel tank body is formed in an end face on the another end side of the fuel tank body; and
the first connector is provided in the recess so as not to project out from the end face on the another end side of the fuel tank body.

4. The fuel tank of claim 1 , wherein the first connector includes:
a supply port through which fuel is supplied to the fuel-powered device; and
a filler port through which fuel is filled into the fuel tank body.

5. The fuel tank of claim 1 , further comprising a remaining fuel level display section configured to display a remaining level of fuel in the fuel tank body.

6. The fuel tank of claim 5 , wherein the remaining fuel level display section is provided at a position visible from outside the fuel-powered device in a state in which the fuel tank body has been installed to the fuel-powered device.

7. The fuel tank of claim 1 , wherein the cover member includes a remaining fuel level display section configured to display a remaining level of fuel in the fuel tank body.

8. The fuel tank of claim 1 , further comprising a lock section projecting from an outer circumferential face of the tank body.

9. The fuel tank of claim 8 , wherein the lock section is formed at a same circumferential position as an end portion of the handle, and the lock section is axially spaced from the end potion of the handle.

10. A fuel tank comprising:
a cylindrical fuel tank body provided so as to be detachably attachable to a fuel-powered device, the fuel tank body having one end side and another end side, the one end side and the another end side being in a length direction of the fuel tank body;
a recess at the one end side of the fuel tank body;
a handle formed on the one end side of the fuel tank body, the handle disposed in the recess;
a first connector formed on the another end side of the fuel tank body and configured such that, by installing the fuel tank body to the fuel-powered device, the first connector is connected to a second connector provided at the fuel-powered device so as to enable fuel to be supplied to the fuel-powered device; and
a lock section projecting from an outer circumferential face of the tank body, the lock section is formed at a same circumferential position as an end portion of the handle, and the lock section is axially spaced from the end potion of the handle.
