The present invention relates to a massage pin for skin blood circulation promoters. More particularly, the present invention relates to a massage pin for skin blood circulation promoters, which has a lower end to/from which a silver conductor having stable electrical resistance is coupled or separated by a user of a skin blood circulation promoter, as needed. The massage pin according to the present invention includes: a coupling portion (171) formed at an upper end of the massage pin and press-fitted into a circuit board (130) disposed between a main body (110) and a cover (120) of a blood circulation promoter (100), the coupling portion (171) being formed of a conductive rubber; and an exposed portion (172) extending from a lower end of the coupling portion (171) and exposed outside through a massage pin-passage hole (122) formed through the cover (120), the exposed portion (172) being formed of a conductive rubber, wherein the exposed portion (172) has a downwardly tapered connection portion (173) extending from a lower end thereof and including a silver conductor (174) detachably coupled to the connection portion (173), the conductor (174) has a reception portion (174a) open at an upper portion thereof, an inner diameter of the reception portion (174a) of the conductor (174) is smaller than an outer diameter of a middle portion of the connection portion (173), and an outer diameter of the connection portion (173) is smaller than an outer diameter of the exposed portion (172). |
