Abstract
A marking device that targets a fastened member and a fastening member (5,6), the marking device comprising; a housing that covers the fastening member (5, 6); and a marking member that is coupled to the housing via a support shaft (30) and is swingable toward the fastening member (5, 6), characterized in that when a vector having, as a start point, a marked corner part (MC1) and having the swing center (31) as an end point at is a first vector (V1a), and a vector having the marked corner part (MC1) as a start point, and is directed in a direction orthogonal to a central axis (C) of the fastening member (5) and away from the fastening member (5, 6) is a second vector (V2a), an angle (θ1) formed by these two vectors (V1a, V2a) is equal to or greater than 90 degrees and less than 180 degrees.
Claims4
A marking device (1A, 1B) that targets, as marking objects, a fastened member (81) and a fastening member (5, 6, 7) fastened to the fastened member (81), the marking device (1A, 1B) comprising:
- a housing (10A, 10B) that covers the fastening member (5, 6, 7);
- and a marking member (200A, 200B) that is coupled to the housing (10A, 10B) via a support shaft (30) and is swingable toward the fastening member (5, 6, 7) with the support shaft (30) as a swing center (31), characterized in that
- when a vector having, as a start point, a marked corner part (MC1, MC2, MC3) that is a part to which a mark is put in a boundary between the marking objects, and having the swing center (31) as an end point at is a first vector (V1a, V1b, V1c), and
- a vector having the marked corner part (MC1, MC2, MC3) as a start point, and is directed in a direction orthogonal to a central axis (C) of the fastening member (5) and away from the fastening member (5, 6, 7) is a second vector (V2a, V2b, V2c),
- an angle formed by the first vector (V1) and the second vector (V2) is equal to or greater than 90 degrees and less than 180 degrees.
