Claims (1)

[Scope of Claim for Utility Model Registration] A vehicle entrapment prevention device that controls the elevation of an entrapment prevention member disposed on the side of a vehicle body within a lifting range limited by a stopper, which an elevating actuating means that is integrally included and operates by the driving force of the drive source to raise and lower the entrainment prevention member; and a manual operation means for starting the operation of the elevating actuating means, the elevating actuating means further integrally includes an operation stop means for automatically stopping the lifting operation based on an increase in the operating load due to the lifting of the entrainment prevention member reaching the limit of the lifting tolerance range,
Vehicle entrapment prevention device.
