The ear hook part has one end located in front of the ear when worn, and the other end located behind the upper back side of the ear helix. It has a lower ear hook member 2 located at the rear through the back side of the ear. The headphone unit 3 is supported within a housing 5 having a support arm 4. A spline shaft 6 is inserted into the tip of the support arm 4. The shaft portion of the spline shaft 6 is provided with a plurality of keyways 7 formed in the axial direction at equal angles, and a female thread 9 formed at the center of the shaft end so that a male thread 8 is screwed into the shaft. ing. A through hole 10 through which the spline shaft 6 is inserted is bored at one end of the upper ear hook member 1, and a knurling consisting of a plurality of concave and convex portions arranged radially is provided inside one opening edge of the through hole. Teeth 11 are formed. Furthermore, an annular rib 19 is provided upright on the opening edge on the side of the knurled teeth 11. Through hole 10
Inside the spline shaft 6, a washer 13 having a plurality of keys 12 formed to fit into each keyway 7 slides in the axial direction via the keys 12 in a state in which it cannot rotate relatively. possible to be installed. Knurled teeth 14 that mesh with the knurled teeth 11 are formed on the surface of the washer 13 facing the knurled teeth 11 of the through hole 10. Moreover, between the washers 13 and the lower ear hook member 2,
A coil spring 15 is inserted to bias the washer 13 toward the upper ear hook member 1. On the other hand, a boss 16 that fits into each keyway 7 of the spline shaft 6 is protruded from one end of the lower ear hook member 2, and a through hole 17 into which the male screw 8 is inserted is bored in the center of the boss 16. ing. Further, a concave stepped portion 18 is formed in the opening of the lower ear hook member 2 and is slidably fitted into the rib 19. The male thread 8 is screwed into the female thread 9 of the spline shaft 6, and thereby the upper ear hook member 1 and the lower ear hook member 2 are rotatably attached. Note that reference numeral 20 is an O-ring interposed between the spline shaft 6 and the support arm 4.

As described above, the boss 16 of the lower ear hook member 2 fits into the key groove 7 of the spline shaft 6, and the key 12 of the washer 13 fits into the key groove 7 of the spline shaft 6.
, the lower ear hook member 2 and washer 13 rotate integrally via the spline shaft 6. In that case, the knurled teeth 14 of the washer 13 are pressed against the upper ear hook member 1 by the spring 15.
Since the upper ear hook member 1 and the lower ear hook member 2 are pressed against the knurled teeth 11 of the upper ear hook member 1, the upper ear hook member 1 and the lower ear hook member 2 can be rotated in small increments with a click feeling. Therefore, depending on the size of the user's ears,
The upper ear hook member 1 and the lower ear hook member 2 can be adjusted so as to sandwich the ear.
