To provide a compact shaft support structure having high durability, and to provide a power transmission device.SOLUTION: A support structure of a shaft fixed to a rotary member disposed in a case includes: a cylindrical shaft support part which is formed at the case and into which the shaft is inserted; a cylindrical extension part which extends from the rotary member so as to enclose the shaft support part of the case from the outer side; and a thrust radial bearing disposed between the shaft support part and the extension part in a radial direction. The extension part, the thrust radial bearing, the shaft support part, and the shaft axially overlap when viewed from the radial direction.SELECTED DRAWING: Figure 5
【課題】高い耐久性を有するコンパクトなシャフトの支持構造および動力伝達装置を提供する。【解決手段】ケース内に配置される回転部材に固定されたシャフトの支持構造は、ケースに形成され、シャフトが挿通される筒状のシャフト支持部と、回転部材からケースのシャフト支持部を外側から包囲するように延出された筒状の延出部と、シャフト支持部と延出部との径方向における間に配置されたスラストラジアル軸受とを含み、延出部、スラストラジアル軸受、シャフト支持部およびシャフトは、径方向からみて軸方向に重なる。【選択図】図5
