<p>PURPOSE:To reduce the size and weight by providing a special metal jig with a hole for fixing a looseness adjusting tool being used when the interval of a vernier metal is adjusted thereby decreasing the number of parts. CONSTITUTION:The body 10a of a special metal jig A1 is provided, on one end side thereof, with a clevis 2 for coupling a compression clamp and, on the other end side thereof, with a clevis 5 for coupling a metal 4 coupled with a vernier metal C and a hole 11 for fixing a looseness adjusting tool D is made on the clevis side of the body 10a. Since conventional fixing metal is not required between the body 10a and the vernier metal C when the special metal jig A1 is used, the number of parts can be decreased and the size and weight can be reduced in the vicinity of the special metal jig A1.</p> |
