Abstract: A knee guard on the passenger side of a vehicle includes left and right knee guard brackets disposed along left and right side faces of a glove box and secured at a front end thereof to a steering support beam, a connecting member transversely connecting these left and right knee guard brackets and a closure member of the glove box. The closure member includes a reinforcement therein and the reinforcement has a closed cross section which extends in the widthwise direction of the vehicle. When the knees of a passenger abut against the closure member of the glove box in the event of a head-on impact, the closure member is displaced forwardly and abuts against the left and right knee guard brackets, thereby an impact load is transmitted to the knee guard brackets.
