Vehicle reinforcement member and vehicle center pillar

An elongate vehicle reinforcement member having a U-shaped cross section, wherein the vehicle reinforcement member is disposed inside a vehicle structural member and welded to the vehicle structural member, wherein the vehicle structural member comprises opposite base lateral walls,

• the vehicle reinforcement member comprising:
• opposite reinforcement lateral walls extending in vehicle height and width directions, each having an outward edge on an outer side in vehicle width direction and an inward edge on an inner side in vehicle width direction, wherein the reinforcement lateral walls are placed along inner sides of the base lateral walls of the vehicle structural member;
• and
• a reinforcement connecting wall connecting the outward edges of the reinforcement lateral walls,
• each reinforcement lateral wall together with the reinforcement connecting wall forming a ridge,
• each reinforcement lateral wall comprising a row of welding projections, each welding projection protruding outward over the entire width of the reinforcement lateral wall from the ridge to the inward edge of the reinforcement lateral wall,
• each welding projection having a raised welding surface at which the reinforcement lateral wall is welded to the base lateral wall,
• the welding projections in each row being arranged at intervals along vehicle height direction.
