Provided is a technology with which attachment properties of a liquid supply unit with respect to a liquid jetting device are improved. A first cartridge (100a) is attached to a carriage of a printing device via a holder (200). The holder (200) is provided with a lever (230) which rotates to engage with a main engagement section (120) of the first cartridge (100a). The first cartridge (100a) is provided with a first side wall section (125) and a second side wall section (126) which, when the first cartridge (100a) is attached to the holder (200), press against the lever (230) and cause the lever (230) to rotate towards a front side. When the first cartridge (100a) is attached, a rotational axis (RX) of the lever (230) is positioned closer to ink supply ports (110, 110a) than the first side wall section (125) and the second side wall section (126). |
