PROBLEM TO BE SOLVED: To provide a driver in which intrusion of water and the like can be prevented.SOLUTION: A shaft 10 of a driver 1 is supported rotatably by a first bearing 31 and a second bearing 32. The first bearing 31 is provided on the inner wall of a shaft hole 26 made in an output side frame end 22. The second bearing 32 is provided on the inside of a bearing box 27 in an anti-output side frame end 23. An oil seal 34 is fixed to the inner wall of the shaft hole 26 on the side closer to an output end 11 side than the first bearing 31, and slides on the outer periphery of the shaft 10. A biasing member 33 is housed in the bearing box 27, and biases the outer ring of the second bearing 32 to the output end 11 side. Consequently, shake and deflection of the shaft 10 can be reduced at a place where the oil seal 34 is installed.SELECTED DRAWING: Figure 2

    【課題】水等の浸入を防ぐことの可能な駆動装置を提供する。【解決手段】駆動装置1が備えるシャフト10は、第1軸受31と第2軸受32とにより回転可能に支持される。第1軸受31は、出力側フレームエンド22が有する軸孔26の内壁に設けられる。第2軸受32は、反出力側フレームエンド23が有する軸受ボックス27の内側に設けられる。オイルシール34は、第1軸受31よりも出力端11側で軸孔26の内壁に固定され、シャフト10の外周に摺接する。付勢部材33は、軸受ボックス27に収容され、第2軸受32の外輪を出力端11側に付勢する。これにより、オイルシール34が設置された箇所におけるシャフト10の振れ量および撓み量を小さくすることが可能である。【選択図】図2
