PROBLEM TO BE SOLVED: To provide a traveling transmission device of a working vehicle in which a parking brake can be operated manually and easily.SOLUTION: A traveling transmission device of a working vehicle is configured as follows: left and right shift cylindrical bodies (3, 3) for traveling power transmission are slidably fitted to a spindle (2a) integrally including a drive gear (2) in the left and right center; left and right compression springs (4, 4) for compressing inward these shift cylindrical bodies (3, 3), respectively, are used for clutch coupling between the shift cylindrical bodies (3, 3) and the drive gear (2), and traveling power is transmitted to the shift cylindrical bodies (3, 3); also, the transmission of the clutch is interrupted by shifter operation and left and right brake members (5, 5) for exerting rotational braking force to the shift cylindrical bodies (3, 3) are configured to be included; operation plates (6, 6) disposed in the outside left and right of the shift cylindrical bodies (3, 3) are moved in the axial direction of the spindle (2a), and pressing bodies (7, 8) for operating the brake members (5, 5) are provided; and thereby parking brake operation is made easily.SELECTED DRAWING: Figure 1

    【課題】手動で容易に駐車ブレーキを操作することができる作業車両の走行伝動装置を提供する。【解決手段】作業車両の走行伝動装置は、駆動ギヤ(2)を左右中央に一体に備える主軸(2a)に走行動力伝動用の左右のシフト筒体(3,3)を摺動可能に嵌合し、これらシフト筒体(3,3)をそれぞれ内方に弾圧する左右の圧縮バネ(4,4)により、前記シフト筒体(3,3)と前記駆動ギヤ(2)との間をクラッチ結合して走行動力を前記シフト筒体(3,3)に伝動し、また、シフタ操作によりクラッチの伝動を遮断するとともに、前記シフト筒体(3,3)に回転制動力を作用する左右の制動部材(5,5)を備えて構成され、前記シフト筒体(3,3)の外側左右に配置した操作プレート(6,6)を前記主軸(2a)の軸線方向に移動させて前記制動部材(5,5)を作動させる押圧体(7,8)を設けることにより駐車ブレーキ操作を容易とするものである。【選択図】図1
