  • Patent number: 11499351
    Abstract: A striker mounting structure is designed to mount a striker on a vehicle body and prevent a door from entering a passenger compartment. A reinforcement provided on the vehicle body is covered by an outer panel. A striker mounting surface is arranged to be spaced away from the reinforcement in a front/backward direction of the vehicle body. The reinforcement is provided with an insertion hole opening toward a direction away from the passenger compartment. The striker and a reinforcement member are fixed to opposite sides of the striker mounting surface. A connecting rod is fixed to the reinforcement member and is formed with a locking portion extending into the insertion hole in a direction toward the passenger compartment and formed with an abutment portion. A distance between an end of the abutment portion and the passenger compartment is smaller than a distance between the striker and the passenger compartment.
