Abstract

A fuel tank comprises a circular column-shaped fuel tank body, a handle, and a lock mechanism. The circular column-shaped fuel tank body is provided so as to be capable of being detachably attached to a fuel-powered device. The handle is formed on one end side in a length direction of the fuel tank body. The lock mechanism is capable of switching between a locked state in which the fuel tank body cannot be removed from the fuel-powered device, and a lock-released state in which the locked state has been released, due to the fuel tank body being rotated in a circumferential direction in a state of being installed to the fuel-powered device.

First claim

What is claimed is:

1. A fuel tank comprising:
a circular column-shaped fuel tank body provided so as to be capable of being detachably attached to a fuel-powered device;
a handle formed on one end side in a length direction of the fuel tank body;
a lock mechanism that is capable of switching between a locked state in which the fuel tank body cannot be removed from the fuel-powered device, and a lock-released state in which the locked state has been released, due to the fuel tank body being rotated in a circumferential direction in a state of being installed to the fuel-powered device; and
a recess indented in the length direction on the one length direction end side of the fuel tank body, the recess is formed in a cover member that is capable of being detachably attached to the fuel tank body,
wherein the handle is provided inside the recess.

2. The fuel tank of claim 1 , wherein the handle is integrally provided at the fuel tank body.

3. The fuel tank of claim 1 , wherein the handle is provided so as not to project out from an end face on the one end side of the fuel tank body.

4. The fuel tank of claim 1 , wherein the handle is formed so as to extend in a long thin shape along a radial direction of 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.
