PROBLEM TO BE SOLVED: To ensure a crash stroke by surely separating a rear differential having a vibration reduction weight from a vehicle body frame at the time of a head-on collision of a vehicle.SOLUTION: In a support structure of a rear differential, a shaft member 21 is mounted forward from a bracket 12 mounted on a rear differential, an outer peripheral part of the shaft member is inserted from the front end into a through hole 14d of a rubber mount 14 supported on a vehicle body, a through hole 22a of a vibration reduction weight 22 and washer 23 in this order and is fitted thereto, the rubber mount, the vibration reduction weight and the washer are supported on the shaft member by a fixing member 24 mounted to the front end of the shaft member, and an outer peripheral part of the rubber mount is supported on the vehicle body frame. The outer diameter of the fixing member is set smaller than the inner diameter of the through hole of the rubber mount and the inner diameter of the through hole of the vibration reduction weight.SELECTED DRAWING: Figure 3

    【課題】車両の前面衝突時に防振ウエイトを有するリヤディファレンシャルを車体フレームから確実に分離してクラッシュストロークを確保する。【解決手段】リヤディファレンシャルに装着したブラケット12から軸部材21が前方に向かって装着され、軸部材の前端から外周部を車体フレームに支持されるラバーマウント14の貫通孔14d、防振ウエイト22の貫通孔22aおよびワッシャ23の順に挿入されて嵌合し、軸部材の前端に装着された固定部材24により軸部材上にラバーマウント、防振ウエイトおよびワッシャが支持され、ラバーマウントの外周部が車体フレームに支持されるリヤディファレンシャルの支持構造において、固定部材の外径はラバーマウントの貫通孔の内径および防振ウエイトの貫通孔の内径よりも小さくする。【選択図】図3
