PURPOSE: To cool a fused plastic material leaking through a grand packing with no affection upon a pump body so as to safely solidify a fused plastic material.
CONSTITUTION: In a shaft seal device 1, a packing retainer 9 located laterally of a packing box 3, is composed of a cylindrical part 9a abutting against a grand packing loosely fitted on a shaft 3, a body 9b integrally incorporated with a body 9b, and a bolt 10 and a nut 11 screwed onto the nut 11, by which the degree of fastening the grand packing 4 can be adjusted. An annular jacket chamber 13 is formed in the body 9b, surrounding around a gap between the body 9b and the shaft 3. An accumulating chamber 16 communicated with the gap 12, and a discharge port 17 communicated with the accumulating chamber 16 and opened downward, are formed in the body 9b.
