<P>PROBLEM TO BE SOLVED: To provide a work machine capable of preventing an angle detector from being damaged and accurately calculating an attachment posture. <P>SOLUTION: A work machine includes: angle detection means (16) for detecting an internal angle θ<SB POS="POST">1</SB>with an engaging pin (15) as an apex among the internal angles of a triangle formed by connecting the engaging pin (15), a second connection pin (22), and a fourth connection pin (24) with straight lines with each other; cylinder drive direction determination means (31) for determining whether a stroke position of a hydraulic cylinder (9) is present on an extension side or on a contraction side of a threshold where an internal angle θ<SB POS="POST">2</SB>with a fourth connection pin of the triangle as an apex becomes 90 degrees; and attachment posture angle calculating means (32) for calculating an internal angle θ<SB POS="POST">ATT</SB>with a first connection pin as an apex among the internal angles of a quadrangle formed by connecting the first connecting pin, the second connecting pin, a third connecting pin, and the fourth connecting pin with straight lines with each other, on the basis of the internal angle θ<SB POS="POST">1</SB>and a determination result of the cylinder drive direction determination means. <P>COPYRIGHT: (C)2013,JPO&INPIT |
