PROBLEM TO BE SOLVED: To solve the problem of lacking even braking force, by hardly making access to a parking brake device, in a four-wheel drive vehicle for providing a PTO takeout unit on the left-right one side of a transmission case.SOLUTION: A four-wheel drive vehicle 80 comprises a driving system gear train 69 for driving rear axles 5 and 5 for travel, power takeout units 15, 15A and 15B for outputting power from a counter shaft 16 in the middle of the driving system gear train 69 from a PTO output shaft 26 via a PTO system gear train 70 from PTO input shafts 25 and 25A as PTO power and parking brake devices 41, 41A and 100 for braking rotation of the rear axles 5 and 5, and installs the power takeout units 15, 15A and 15B on the left-right one side of a transmission case 10a for storing the driving system gear train 69, and the parking brake devices 41, 41A and 100 are arranged on the counter shaft 16 or the PTO input shafts 25 and 25A between the driving system gear train 69 and the PTO system gear train 70.SELECTED DRAWING: Figure 2

    【課題】ミッションケースの左右一側にPTO取出用のユニットを設けた四輪駆動車両では、駐車ブレーキ装置にアクセスしにくく、制動力も不足する、という問題があった。【解決手段】走行用の後車軸5・5を駆動する駆動系ギア列69と、駆動系ギア列69途中のカウンタ軸16からの動力をPTO動力としてPTO入力軸25・25AからPTO系ギア列70を介してPTO出力軸26より出力する動力取り出しユニット15・15A・15Bと、後車軸5・5の回転を制動する駐車ブレーキ装置41・41A・100とを備え、動力取り出しユニット15・15A・15Bを、駆動系ギア列69を収容するミッションケース10aの左右一側に装着した四輪駆動車両80において、駐車ブレーキ装置41・41A・100は、駆動系ギア列69とPTO系ギア列70との間のカウンタ軸16またはPTO入力軸25・25A上に配置した。【選択図】図2
