Abstract:
1. A pulse tube cryogenic cooler, comprising: a cold storage device cartridge whose high temperature end is connected to a pressure change source; a pulse tube whose low temperature end is connected to a low temperature end of the cold storage device cartridge via a stage member; a phase adjusting mechanism connected to a high temperature end of the pulse tube; a flange where the phase adjusting mechanism is provided; and a cold storage device cylinder provided between the flange and the stage member, the cold storage device receiving the cold storage device cartridge; wherein a projection part where a connection hole configured to connect with the pulse tube is formed is provided at the low temperature end of the cold storage device cartridge so as to project to the stage member; an installing concave part where the projection part is movably installed is formed in the stage member; and a cross-sectional area of the installing concave part is smaller than a cross-sectional area of the cold storage device cartridge, wherein a gap part is provided between a container main body and the cold storage device cartridge; and the gap is larger than a relative displacement between the container main body and the cold storage device cartridge.
