Document Type and Number:
WIPO Patent Application WO/2017/187894
Kind Code:
A1
Abstract:
Provided is a portable cutting machine that increases the amount that a main body rotates with respect to a base without a tilting mechanism being enlarged or increased in weight. A circular saw in which a base and a main body that comprises a rotating blade are connected so as to be capable of relative rotation. The circular saw has: a connection member 21 that connects the base and the main body such that the base and the main body are capable of relative rotation; a bevel stand 30 that is provided to the base; a first long hole 31 that is provided in the bevel stand 30; a bevel plate 40 that is provided to the main body; a second long hole 41 that is provided in the bevel plate 40 and that communicates with the first long hole 31; and a through member 50 that passes through the first long hole 31 and the second long hole 41 and that moves along the first long hole 31 in association with the rotation of the main body. The second long hole 41 extends in a direction that allows the through member 50 to move toward the connection member 21 when the former has reached one end of the first long hole 31. The second long hole 41 extends in a direction that intersects a straight line that connects the center of the connection member 21 and the center of the through member 50.
