The pop-up hood unit is deformable due to an input of an impact upon a collision with a target for protection. The pop-up hood unit is shaped as a plate that extends in a left-right direction of the vehicle body and has a plate surface having an inclination angle that is variable relative to a horizontal plane. ## Claims ### Claim 1 A vehicle body front structure comprising: a pop-up hood unit disposed on a front end portion of an enginehood of a vehicle body and configured to translate upward above the enginehood by using a lift-up mechanism, wherein the pop-up hood unit is deformable due to an input of an impact upon a collision with a target for protection, wherein the pop-up hood unit is shaped as a plate that extends in a left-right direction of the vehicle body, and wherein the pop-up hood unit has a plate surface having an inclination angle that is variable relative to a horizontal plane. ### Claim 2 (depends on 1) The vehicle body front structure according to claim 1, further comprising: a bag unit configured to deploy on the enginehood of the vehicle body by a gas from an inflator, wherein the bag unit deploys on the enginehood through an opening that is formed at the front end portion of the vehicle body with the pop-up hood unit moved upward. ### Claim 3 (depends on 2) The vehicle body front structure according to claim 2, wherein the bag unit is configured to deploy in contact with the pop-up hood unit while being guided by the pop-up hood unit. ### Claim 4 (depends on 1) The vehicle body front structure according to claim 1, further comprising: a detection device configured to detect a situation in front of the vehicle body; and a control unit configured to operate the lift-up mechanism by predicting a collision with the target for protection based on a detection of the detection device. ### Claim 5 (depends on 1) The vehicle body front structure according to claim 1, wherein the pop-up hood unit is configured to translate upward above the enginehood by moving in a substantially linear upward direction by using the lift-up mechanism. ### Claim 6 (depends on 1) The vehicle body front structure according to claim 1, wherein the lift-up mechanism comprises support rods that engage the pop-up hood unit and are configured to be driven in a substantially linear upward direction so as to translate the pop-up hood unit in the substantially linear upward direction to dispose the pop-up hood unit upward above the enginehood.
