1. An aerosol generation device comprising:
a power source;
an accommodation portion having a cylindrical shape and configured to store an aerosol source;
a suction port part formed with a suction port configured to suck an aerosol made from the aerosol source atomized;
a connector connecting the power source, the accommodation portion, and the suction port part in an axial direction extending a central axis of the main body unit is provided; and
a cartridge configured to accommodate the aerosol source and inserted into the accommodation portion of the main body unit to be rotatable around the central axis; and
a first rotation restriction portion configured to restrict a relative rotation of the cartridge with respect to the accommodation portion,
wherein the connector comprises a first rotation connector configured to release a connection between the power source and the accommodation portion by applying a first torque around the central axis, and a second rotation connector configured to release a connection between the accommodation portion and the suction port part by applying a second torque smaller than the first torque around the central axis, and
wherein the first rotation restriction portion comprises:
a first convex provided at either one of the cartridge or the power source and extend toward the other in the axial direction; and
a first concave portion provided at the other of the cartridge or the power source and into which the first convex is insertable in the axial direction,
wherein the first convex and the first concave portion are formed on a same radius with the central axis as a center.
