Document Type and Number:
WIPO Patent Application WO/2013/014737
Kind Code:
A1
Abstract:
The problem addressed by the present invention is to provide a saw sheath whereby the insertion of a saw is easy and smooth, the cutting edge does not become caught or the like at an inner wall, and thus it is possible to reduce the cutting away of the inner wall of the sheath by the saw blade. The saw sheath (1) is provided with a flat sheath opening section (10) and a main sheath body (20), and the saw blade (31) is inserted into the main sheath body (20) via the sheath opening section (10). The sheath opening section (10) has an opening width that is wider at the entrance and becomes narrower further inside. A pair of first guide rollers (11a) are provided to both sides in the widthwise direction of the entrance to the sheath opening section (10), a pair of second guide rollers (11b) are provided to both sides in the widthwise direction of the inner aperture of the sheath opening section (10), and a pair of third guide rollers (11c) are provided to the two sides perpendicular to the widthwise direction at the intermediate position between the first guide rollers (11a) and the second guide rollers (11b).
