An instrument for measuring dimensions of a can seam portion comprising a criterion measuring pin (9), a linear gauge (10) provided with a measuring spindle (12) which is so supported as to be movable along straight line (L) in the direction of approaching said criterion measuring pin (9) and in the direction of leaving said criterion measuring pin (9), a can cap supporting block (6), and a can body supporting block (7). The can cap supporting block (6) holds the can such that the direction of measuring can seaming thickness (T) may be identical with the above straight line (L) and the inner face of the can seam portion may contact said criterion measuring pin (9). The can body supporting block (7) holds the can such that the direction of measuring can seaming width (W) may be identical with the above straight line (L) and the lower face of the can seam portion may contact said criterion measuring pin (9). |
