Abstract: A waist sporting equipment has a circular ring member sized to encircle around the waist portion of a user and having a predetermined cross-section, an inertia member of a predetermined weight for applying the centrifugal force and inertia force gradually to the ring member upon rotation of the ring member, the inertia member including a weight body and connecting means for connecting the ring member and the inertia member for not separating the members upon the rotation of the members. The weight body is spaced a predetermined distance from the ring and applies the centrifugal force and the inertia force to the ring depending on the rotational velocity of the ring, thus giving a user various velocity and amusement feeling. Furthermore, the centrifugal force acts on the waist portion so that the waist may be stronger and limber and the body of the user may be well balanced.

Abstract: A tape loading device for high-speed search of a VCR which is designed to exactly search out a position of a program recorded on the tape by the user, and it comprises a loading gear provided with a teethless part and a projection, a rotating body provided with a pair of locking jaws spaced with a predetermined angle each other, and a loading arm connected with the rotating body by a bush to transmit the rotation force from the loading gear to a slant post assembly.
