PURPOSE:To facilitate separation and joint operation of a transmission case by installing an indication at a specific position on a connection body such as slide coupling which can be revolved integrally with a transmission shaft when the notched part of a clutch gear is separated in the direction of shaft core. CONSTITUTION:In the captioned transmission mechanism, an intermediate transmission case 3 is interposed between the front and the rear transmission cases 1 and 2, and the rear part of the transmission shaft 6 of a transmission mechanism H is axially supported onto the front wall 3b of the intermediate case 3 through a bearing 8. The transmission shaft 14 of a transmission mechanism M is axially supported onto the rear part of the above-described transmission shaft 6 and the bearing body 15 of the intermediate case 3 through bearings 16 and 17, and the transmission shaft 14 is revolved at high speed or in the reverse direction by allowing a slide coupling 27 to be selectively engaged or disengaged onto a clutch gear 6b or 22a by a shifter 29. A notched part is formed on a part of the clutch gear 6b, and an indication I2 to form a notched part for the coupling 27 is installed at the position in a phase different by 180 deg. for the above-described notched part. |
