PROBLEM TO BE SOLVED: To provide a vehicular suspension device capable of preventing trouble in an electromagnetic motor type restraint generator by preventing a short-circuited state under normal motor output due to rapture or the like of a switching element.SOLUTION: In a vehicular suspension device employing an electromagnetic motor type shock absorber, a restraining force control circuit 31 is provided which controls output torque by controlling a current output from a restraining force generator 6. A battery 30 and the restraining force control circuit 31 are connected in parallel to the restraining force generator 6. The restraining force control circuit 31 includes a switching element 34 and a protection circuit 35. The switching element 34 is capable of switching a connection to one of a passage (1) in which the current output from the restraining force generator 6 flows to the side of the restraining force control circuit, and a passage (2) where the current flows to the side of the battery. The protection circuit 35 is connected in series to the switching element 34 and prevents an overcurrent to the restraining force generator 6. |
