PROBLEM TO BE SOLVED: To provide a device which facilitates the adjustment of an end play, reduces the number of part items, and can easily perform work.SOLUTION: A two-motor vehicle drive unit comprises two sets of reduction gears 2L, 2R which individually reduce the power of two sets of electric motors 1L, 1R for independently driving left and right drive wheels, and transmit the power to the left and right drive wheel. A reduction gear casing 20 is composed of a center casing 20a and left and right side-face casings 20bL, 20bR which are fixed to both side faces of the center casing 20a. In the center casing 20a, a partitioning wall 21 is arranged in a center, and the center casing is divided into two accommodation chambers 22L, 22R by the partitioning wall 21, bearing holes composed of penetration holes are formed at a boss part of the partitioning wall 21 of the center casing 20a, a spacer 10 is arranged between bearings 28a, 28a which are attached to left and right shafts fit into the bearing holes of the center casing, and the spacer 10 is sandwiched between both the bearings 28a, 28a.SELECTED DRAWING: Figure 1
【課題】エンドプレイの調整を容易にすると共に、部品点数を減らし、作業を容易に行うことができる装置を提供する。【解決手段】左右の駆動輪を独立に駆動させる2基の電動モータ1L,1Rの動力を個別に減速して左右の駆動輪に伝達する2基の減速機2L,2Rとを備え、減速機ケーシング20は、中央ケーシング20aと中央ケーシング20aの両側面に固定される左右の側面ケーシング20bL,20bRからなり、中央ケーシング20aには、中央に仕切り壁21が設けられ、仕切り壁21によって左右に2つの収容室22L,22Rに分割し、中央ケーシング20aの仕切り壁21のボス部には、貫通穴からなる軸受穴が設けられ、中央ケーシングの軸受穴に嵌め込まれる左右の軸に取り付けられた軸受28a,28a間にスペーサ10を配し、スペーサ10を両軸受28a,28aで挟み込む。【選択図】図1
