To provide a mounting structure for a vehicular suspension, which is able to improve torsion rigidity of a mounting member.SOLUTION: A mounting structure for a vehicular suspension comprises: a vehicle rear member having a bottom part 111 and a pair of upward extending parts 112; a bracket 20 having side parts 21 suspending from both ends, in a vehicle width direction, of the bottom part 111, and a bent part 22 connected to front ends of the pair of side parts 21 and directed in forward and backward directions of the vehicle; a support shaft 31 allowed to communicate with the pair of side parts 21; and an auxiliary rigid member 40 having a first auxiliary rigid part 41 and a second auxiliary rigid part 42. A first hollow area 51 crossing the boundary between the upward extending parts 112 and the side parts 21 and extending in the forward and backward directions of the vehicle is provided between the upward extending parts 112 and side parts 21 and the first auxiliary rigid part 41. A second hollow area 52 extending in a vertical direction of the vehicle and communicating with a front end of the first hollow area 51 is provided between the boundary between the side parts 21 and bent part 22 and the boundary between the first auxiliary rigid part 41 and the second auxiliary rigid part 42.SELECTED DRAWING: Figure 1 【課題】 取付け部材のねじり剛性の向上を図ることが可能な車両用サスペンションの取付け構造を提供する。【解決手段】 底部１１１および一対の起立部１１２を有する車両後方部材と、底部１１１の車幅方向両端から下垂する側部２１、および一対の側部２１の前端につながり、かつ車両前後方向を向く屈折部２２、を有するとともに、車両後方部材に接合されたブラケット２０と、一対の側部２１に連通された支持軸３１と、第１補剛部４１および第２補剛部４２を有する補剛材４０と、を備え、起立部１１２および側部２１と、第１補剛部４１との間には、起立部１１２と側部２１との境界を跨ぎ、かつ車両前後方向に延びる第１中空領域５１が設けられ、側部２１と屈折部２２との境界と、第１補剛部４１と第２補剛部４２との境界と、の間には、車両上下方向に延び、かつ第１中空領域５１の前端に通じる第２中空領域５２が設けられている。【選択図】 図１
