• a front wall adapted to be a leading end surface when the liquid cartridge is inserted into the cartridge mounting section, the front wall having a pair of longitudinal sides and a pair of transverse sides perpendicular to the pair of longitudinal sides, wherein the pair of longitudinal sides are longer than the pair of transverse sides;
• a rear wall opposing the front wall;
• a top wall intersecting with the front wall at a top of one of the pair of longitudinal sides and the rear wall;
• a bottom wall intersecting with the front wall at a bottom one of the pair of longitudinal sides and the rear wall;
• and
• at least one liquid supply port provided on the front wall and adapted to supply the liquid therefrom to at least one liquid supply portion provided on the cartridge mounting section when the liquid cartridge is mounted on the liquid consuming apparatus;
• a first engaging recess and a second engaging recess provided on one of the top wall and the bottom wall, the first and second engaging recesses being located proximate one of the longitudinal sides of the front wall such that the first engaging recess being located between a center in a longitudinal direction of the front wall and a first one of the transverse sides of the front wall, the second engaging recess being located between the center in the longitudinal direction of the front wall and a second one of the transverse sides, the first and second engaging recesses being adapted to be engaged with an engaging member of the cartridge loading/unloading device when the liquid cartridge is inserted into the cartridge mounting section;
• and
• a first abutting part provided in the first engaging recess and adapted to come in contact with the engaging member when the liquid cartridge is inserted into the cartridge mounting section;
• and
• a second abutting part provided in the second engaging recess, and adapted to come in contact with the engaging member when the liquid cartridge is inserted into the cartridge mounting section.
