To provide a vacuum pump-installed type power generator with improved cooling performance capable of largely improving durability of a brush while improving performance of a vacuum pump by preventing deterioration of oil fed into the brush and the vacuum pump by heat radiation effect.
A rotation shaft 4 supported by a bearing 3 is installed on a rear bracket 2 in this power generator 1. On the rotary shaft 4, a housing 5 of the vacuum pump provided with vanes and a rotary rotor is installed. At a lower part of the housing 5, a pump bracket 6 is assembled through the bearing. A packing having gas sealing effect is installed around a center axial hole 7 in the pump bracket 6 to get in contact with the rear bracket 2. A space part 9 to shield transmission of heat is formed between the packing and the axial hole. Plural heat radiation grooves 10 are radially formed in a bottom surface of the pump bracket 6.
