We report the detection of the expansion and inner proper motions of a young radio lobe associated with the bright radio source 3C 84 in the Seyfert galaxy NGC 1275 using multi-epoch VSOP observation. The observed inner proper motions are consistent with the evolution scenario of classical double radio sources. The apparent expansion velocity is 0.50 ± 0.09 c, and the age of radio lobe is estimated to be 45.7 ± 8.9 years in 2001. The total flux density at 5 GHz increased at the end of the 1950's, with several peaks in the middle of the 1980's, and is in a decay phase now. The decay of total flux density can be naturally explained by an adiabatic cooling due to the expansion of the radio lobe, and previously measured spectral indices suggest that the emission comes from the surface of the radio lobe.
