PROBLEM TO BE SOLVED: To provide a dimethyl ether filling device having a rubber sealant exhibiting superior resistance to dimethyl ether and LP gas. SOLUTION: The dimethyl ether filling device is provided with a pressure feeding means for pressure feeding dimethyl ether stored in a storage container, and a filling nozzle for supplying dimethyl ether pressure fed by the pressure feeding means to a container. In the dimethyl ether filling device, the rubber member formed of a rubber composition, which is prepared by blending layer silicate with a terpolymer comprising ethylene,α-olefin, and a diene compound, is used as a rubber member sealing the part to be brought into contact with dimethyl ether.
