PROBLEM TO BE SOLVED: To provide a support structure for coil bobbin having a coil bobbin fitted normally to a rod. SOLUTION: A diameter at a tip of the rod 11 is smaller than the diameter of the entrance of an insertion hole 21a. The rod 11 is provided with a rod-side tapered face 11a gradually formed from the tip of the rod 11 to the middle of the rod 11, and a rod-side straight face 11b formed from the middle of the rod 11 to a base and fitted to the insertion hole 21a. The coil bobbin 2 is provided with a first bobbin-side tapered face 21b, having a required angular pitch angle larger than the rod side tapered face 11a, a second bobbin-side tapered face 21c having the same angular pitch as that of the rod-tapered face 11a, and a bobbin-side straight face 21e formed from the middle of the insertion hole 21a to the exit of the insertion hole 21a and fitted to the rod-side straight face 11b.
