A shaft end gasket has fixed sealed friction ring installed in housing, rotary sealing friction ring with circular boring that is springy installed on shaft, there elastomer circular sealing element with round cross-section is installed, circular support element fixed on shaft with stopper ring, and cylindrical screw compression spring placed between circular support element and rotary friction ring. Circular support element is arranged as shaped support bushing with shoulders fixed to shaft with at least one fixation screw placed with inclination, this has cylindrical section placed in circular boring of rotary sealing friction ring equipped with shoulders, and by means of installed in it in radial position at least one pin it is connected to rotary sealing friction ring. Cylindrical screw compression spring is placed round rotary sealing friction ring between its shoulders and shoulders of support bushing. Circular boring of rotary sealing friction ring at section of its connection to pin is made wider that at the rest of its length, with gradual transition from broad section of circular boring to its narrow section. The end of cylindrical section of support bushing is placed in narrow section of circular boring closely to its side wall.
