It is preferable that the hole is formed in the shape of a long slot.

According to this configuration, when the tightening bolt is loosely tightened with respect to the nut part, the tightening bolt is inserted into the through hole in a state in which the threaded part of the tightening bolt is inserted into the through hole. It becomes easier to swing in two directions. Thereby, it becomes easy to expand one end portion or the other end portion in the second direction of the inner member, in which the threaded portion is screwed into the nut portion, with respect to the outer member. Thus, according to this configuration, the workability of the fixture when fixing the channel material to the material to be fixed can be further improved.

As one aspect,
The inner member has a pair of contact parts that contact the pair of lip parts on both sides of the first direction with the nut part in between,
Preferably, at least one of the pair of abutting portions is formed in an inclined shape so that the distance from the outer member gradually increases toward the distal end side.

According to this configuration, the lip portion can be easily sandwiched between the contact portion and the outer member. Thereby, the work of connecting the fixture to the channel material can be easily performed.

As one aspect,
The inner member has a base portion on which the nut portion is disposed, and a pair of side portions protruding from the base toward the outer member on both sides of the nut portion in the first direction,
It is preferable that each of the pair of side portions has a notch formed so that the tip of the first lip portion, which is one of the pair of lip portions, is engageable.

According to this configuration, with the first lip portion being sandwiched between the outer member and the inner member due to the biasing force of the elastic member, the distal end portion of the first lip portion is engaged with the notch portion of the pair of side portions. can be done. Thereby, the first lip portion can be made difficult to separate from between the outer member and the inner member. In addition, since the fixing tool can be rotated around the tip of the first lip part that is engaged with the notches in the pair of side parts, it is possible to easily connect the fixing tool to the channel material. .
