Claims (1)

[Scope of utility model registration request] An actuator that opens and closes a lid that closes a side opening of a trunk room formed in the vehicle body, and a working fluid flow path between the actuator and a working fluid supply source are connected to a circuit for opening the lid and a working fluid flow path between the actuator and a working fluid supply source. a flow path switching valve that operates to switch the lid to the closing circuit; a pressure reducing mechanism that is interposed in the lid closing circuit to reduce the speed of the lid closing operation; and a detour connected in parallel to the pressure reducing mechanism. a bypass circuit for the lid, a closing circuit switching valve for switching between the bypass circuit and the pressure reducing mechanism, a locking mechanism for releasably locking the lid in the closed position when the lid is closed; lid position detection means for detecting a state in which the lid has moved to a position near the closing position during a closing operation; and a circuit for closing the lid before the lid moves to a position near the closing position during the closing operation. The working fluid in the closing circuit of the lid is guided to the pressure reducing mechanism side, and when it is detected that the lid has moved to a position near the closing position, the closing circuit switching valve is switched and the working fluid in the closing circuit of the lid is switched. A trunk lid opening/closing device comprising: means for controlling a closing operation of the lid leading to the bypass circuit side.
