To provide a center bearing support with a pressure receiving surface part which can prevent damage of an elastic body when the pressure receiving surface part and the elastic body contact and deal with reduction of a diameter of the center bearing support.SOLUTION: A center bearing support 1 includes: an inner ring 11 to which a bearing 2 which holds a shaft is attached; an elastic body 21 connected to the outer periphery side of the inner ring 11; and an outer ring 31 connected to the outer periphery side of the elastic body 21 and attached to the vehicle body side. The center bearing support 1 has a structure in which a pressure receiving surface part 41 which receives an impact weight caused during a vehicle collision is provided at one axial end part of the outer ring 31 and the center bearing support 1 is detached from the vehicle body side when the impact weight is input to the pressure receiving surface part 41. The pressure receiving surface part 41 is formed by combining a pressure receiving member 42, which fits in an inner peripheral surface of the outer ring 31, with an elastic member 43 held by the pressure receiving member 42 and disposed between the pressure receiving member 42 and the elastic body 21.SELECTED DRAWING: Figure 1
【課題】受圧面部と弾性体が接触しても弾性体が破損するのを防止することができ、センターベアリングサポートの小径化に対応することもできる、受圧面部を備えるセンターベアリングサポートを提供する。【解決手段】シャフトを保持するベアリング2を取り付ける内環11と、内環11の外周側に連結された弾性体21と、弾性体21の外周側に連結され、車体側に取り付けられる外環31とを備えるセンターベアリングサポート1であって、外環31の軸方向一方の端部に車両衝突時の衝撃加重を受ける受圧面部41を設け、衝撃加重が受圧面部41に入力したときにセンターベアリングサポート1が車体側から離脱する構造のセンターベアリングサポート1において、受圧面部41が、外環31の内周面に嵌合される受圧部材42と、受圧部材42に保持され、受圧部材42および弾性体21の間に配置される弾性部材43との組み合わせよりなるものとされている。【選択図】図1
