PROBLEM TO BE SOLVED: To provide a speed change gear transmission device for a power vehicle which can be compactly constituted without requiring a dimensional increase in the total length and in the diametrical direction. SOLUTION: This speed change gear transmission device 6 for the power vehicle is constituted by providing a speed change gear transmitter 41, a travel transmitting shaft 46, and a PTO transmitting shaft 63. In this case, the speed change gear transmitter 41 changes the rotation transmitting ratio in the latter part of a power inputting shaft 31. The travel transmitting shaft 46 transmits the power from the speed change gear transmitting body 41 as the traveling power to a rear wheel differential section 32 on the same axis. The PTO transmitting shaft 63 transmits a working machine power which is branched from the power inputting shaft 31 to a PTO shaft 7 of the latter part stationing in parallel with the travel transmitting shaft 46. In a space between the PTO transmitting shaft 63 and the power inputting shaft 31, a PTO clutch 61 which controls the connection/disconnection of the power transmission, and a PTO speed change gear mechanism 62 which switches the rotation transmitting ratio between the outputting shaft 61d of the PTO clutch 61 and the PTO transmitting shaft 63 are provided. The PTO clutch 61 and the PTO speed change gear mechanism 62 are arranged on the front side by avoiding the speed change gear transmitter 41. COPYRIGHT: (C)2007,JPO&INPIT
