A transmission apparatus includes a frame, a rotating disk fitted on the frame, platforms on the rotating disk, an inner rotating member fitted on the frame, a clutch, and an actuating mechanism for moving the clutch; the platforms have clamping jaws for clamping a work piece; the clutch is joined to the inner rotating member, and can be engaged with and disengaged from a transmission gear rotated with a power source; after one of the platforms is secured to the inner rotating member, the actuating mechanism will exert force to separate the clutch from the transmission gear, and the clamping jaws clamp the work piece, and next the clutch is engaged with the transmission gear; thus, the power source causes rotation of the transmission gear, the clutch, the inner rotating member, and said working platform so as to test whether the work piece is positioned in balanced position.
