Abstract

Official abstract text for this publication.

A wheel includes a circular wheel main body and at least one grouser. The at least one grouser is provided along an outer circumference of the wheel main body and has a contact surface capable of drawing a first tangent line. The first tangent line is inclined opposite to a rotational direction of the wheel main body from the center line of the wheel main body.

First claim

Opening claim text (preview).

What is claimed is: 1. A wheel, comprising: a circular wheel main body; and at least one grouser that is provided along an outer circumference of the circular wheel main body and has a contact surface drawing a first tangent line, the first tangent line being inclined opposite to a rotational direction of the circular wheel main body from the center line of the circular wheel main body, wherein the at least one grouser includes a projection member, the projection member being provided to be inclined opposite to the rotational direction of the circular wheel main body from the center line of the circular wheel main body and having the contact surface of a rectangular shape, and the center line of the circular wheel main body and the contact surface of the projection member defines an angle of approximately 90 degrees. 2. The wheel according to claim 1 , wherein the at least one grouser includes 1 to 48 grousers. 3. The wheel according to claim 2 , wherein the at least one grouser includes 24 grousers. 4. A wheel, comprising: a circular wheel main body; and at least one grouser that is provided along an outer circumference of the circular wheel main body and has a first contact surface and a second contact surface, the first contact surface drawing a first tangent line that is inclined opposite to a first rotational direction of the circular wheel main body from a first center line of the circular wheel main body, and the second contact surface drawing a second tangent line that is inclined opposite to a second rotational direction from a second center line of the circular wheel main body, the second rotational direction being a direction opposite to the first rotational direction wherein the at least one grouser includes at least one projection member, the at least one projection member being provided to be inclined opposite to the rotational direction of the circular wheel main body from the first center line of the circular wheel main body and having the contact surface of a rectangular shape, and the first center line of the circular wheel main body and the first contact surface defines an angle of approximately 90 degrees, and the second center line of the circular wheel main body and the second contact surface defines an angle of approximately 90 degrees. 5. The wheel according to claim 4 , wherein the at least one grouser includes a ridge line at which the first contact surface and the second contact surface intersect with each other. 6. The wheel according to claim 4 , wherein the at least one grouser includes 6 grousers.
