Abstract

The present invention relates to a belt installation tool which is to be installed so as to cover at least a part of a first side surface of a pulley, including an attaching part attached along an outer peripheral part of the pulley, an installation part brought into contact with at least a part of the first side surface, a protection part covering at least a part of the first side surface without coming into contact therewith, and a belt holding part protruding on the protection part or on the installation part, in which the protection part covers at least a part of a part having a largest distance in a vertical direction in an area located inside the part with which the installation part comes into contact in the first side surface.

First claim

The invention claimed is:

1. A belt installation tool which is to be installed so as to cover at least a part of a first side surface of a pulley, the belt installation tool comprising:
an attaching part that is attached along an outer peripheral part of the pulley, the outer peripheral part of the pulley facing away from a center of the pulley in a radial direction,
an installation part having an installation part contact surface that is brought into contact with at least a first part of the first side surface of the pulley,
a protection part that covers at least a second part of the first side surface without contacting the first side surface of the pulley, and
a belt holding part that protrudes from the protection part at a radial position closer to the outer peripheral part of the pulley than to a center of the pulley, or from the installation part,
wherein the protection part covers at least a part of the pulley having a largest distance, in a rotational axis direction of the pulley, from a plane defined by the first part of the first side surface, the part of the pulley being disposed within the first part of the first side surface of the pulley in the radial direction, and
wherein the belt holding part does not extend, in the radial direction, beyond a radially outermost portion of the attaching part.

2. The belt installation tool according to claim 1 , wherein the installation part is connected to the protection part in a stepped form.

3. The belt installation tool according to claim 1 , wherein the attaching part has a circular arc form so as to extend along the outer peripheral part of the pulley.

4. The belt installation tool according to claim 3 , wherein the attaching part further comprises a rib part which is fitted to a groove part provided in the outer peripheral part of the pulley.

5. The belt installation tool according to claim 3 , wherein the attaching part has a circular arc length formed to have a central angle being within a range of 30° to 120°.

6. The belt installation tool according to claim 1 , wherein the pulley has a protrusion on the first side surface and the protection part covers at least a part of the protrusion.

7. The belt installation tool according to claim 1 , wherein the belt holding part does not extend, in the radial direction, beyond the outer peripheral part of the pulley.
