Clamp

A clamp for mounting a spiral hanger on a support wire extending in a front-back direction, comprising:

• a first member having a first through hole formed therein, the first through hole penetrating in a right-left direction;
• a second member provided to the left of the first member and having a second through hole formed therein, the second through hole penetrating in the right-left direction and facing the first through hole;
• and
• a fastener inserted through the first through hole and the second through hole and tightening the first member and the second member to each other in the right-left direction, wherein
• the first member has:
• a plate-shaped first base portion having the first through hole formed therein;
• a plate-shaped first connecting portion protruding from the first base portion to diagonally upper left;
• and
• a first supporting portion provided below the first base portion and curved arcuately in such a manner as to project toward the right;
• the second member has:
• a plate-shaped second base portion having the second through hole formed therein;
• a plate-shaped second connecting portion protruding from the second base portion to diagonally upper right, the second connecting portion being provided to overlap with the first connecting portion above the spiral hanger when seen from the front-back direction;
• and
• a second supporting portion provided below the second base portion and curved arcuately in such a manner as to project toward the left;
• the first connecting portion has a first clamping portion facing the second connecting portion in the right-left direction;
• the second connecting portion has a second clamping portion facing the first clamping portion in the right-left direction;
• the first connecting portion and the second connecting portion are twisted clockwise or counterclockwise such that the first clamping portion and the second clamping portion are tilted to the right or to the left with respect to the front-back direction when seen from above;
• and
• the spiral hanger is mounted on the support wire by tightening the first member and the second member by the fastener in a state where the support wire is passed through between the first supporting portion and the second supporting portion and the spiral hanger is passed through between the first clamping portion and the second clamping portion.
