Claims

[Claims for Utility Model Registration] 1. In a transmission for a working vehicle that includes a plurality of transmission shafts parallel to each other within a transmission case, the plurality of transmission shafts described above are arranged in the cross-sectional shape of the transmission case 10. A pair of overlapping and welded sheet metal bearing frame plates 13 and 14 of corresponding shapes are held and supported, and the bearing frame plates are held in one half of the transmission case and the other case half 15 and 16. A transmission for a work vehicle, characterized in that these bearing frame plates and both case halves are clamped and fixed. 2. Utility Model Registration Scope of Claims 1. The transmission for a working vehicle as set forth in claim 1, wherein both of the case halves 15 and 16 are made of synthetic resin or glass fiber. 3. In the transmission for a working vehicle as set forth in paragraph 1 or 2 of the claims for utility model registration,
A positioning member 42 is provided which is fixed to the bearing frame plates 13 and 14 and projects inward from the one and other case halves 15 and 16 described above, and positioning recesses 44 and 45 into which the positioning member fits are provided respectively. A transmission for a working vehicle is provided on the inner surface of the case halves 15 and 16.
