Abstract
A castor with a brake pad is disclosed, wherein the fixing sections and the pressing sections of the brake pad press against the two wheel-side portions of the wheel body, so in addition to providing friction, it can also provide clamping function, as a result, the braking effect can be achieved more easily, and the braking force tends to be even. Furthermore, because the fixing sections and the pressing sections of the brake pad press against the two wheel-side portions instead of pressing against the center of the wheel body, so no extra resistance is generated, and there is no excess wear, thereby extending the service life of the wheel body.
