A tube spacer S formed by bending a wire, includes a plurality of projections 20 and a base-bending portion 21. Each of the projections 20 is inserted between tubes, and has a pair of extending portions 201 extend in X direction and a front-bending portion 202 for connecting both front ends of the pair of extending portions 201. The base-bending portion 21 connects both rear ends of the projections 20 so that the projections 20 are arranged at interval in Z direction. With this structure, manufacturing cost for the tube spacer S can be low, and the tubes can be stably supported. |
