To appropriately fix a cable to a member to be fixed, and at the same time, to reduce the price.

The cable fixing apparatus has a cable bushing 3 for supporting a cable 2 at a specific position, a case 5 where an insertion hole section 4 for inserting the cable bushing 3 is punched, and a nut 6 that is screwed to the cable bushing 3, inserted into the insertion hole section 4 of the case 5 and pinches the case 5 with the cable bushing 3. In this case, a projection 8 is provided on at least one of contact surfaces 7a and 7b, where a cable bushing 3 is brought into contact with the case 5, thus easily preventing slackness in the screw between the cable bushing 3 and nut 6, without using other members, and hence appropriately fixing the cable 2 to the case 5.
