To provide a vehicular suspension device in which the number of parts constituting a connection device is relatively small and steps for assembling the parts are also relatively small.

The connection device 12 is constituted so as to include: an upper fitting 82 mounted to a vehicle body; a bearing 70 for connecting a chamber shell 39 to the upper fitting 82 while allowing the rotation of the chamber shell relative to the vehicle body; a rubber bushing 48 for allowing the relative displacement of a rod retaining cylinder 32 and a rod 41 of a shock absorber by elastic deformation; a stopper 55 outwardly projected toward an inner peripheral part of the rod retaining cylinder; and a press plate 68 having an outer edge 76 outwardly projected to an outer side than an outer periphery of the rod retaining cylinder and an inner edge 74 outwardly projected to an inner side than an inner periphery of the rod retaining cylinder. Thereby, the vehicular suspension device can be provided in which the number of parts constituting the connection device is relatively small and the steps for assembling the parts are also relatively small.
