Zusammenfassung:	A shaft sealing structure includes a V-packing; a first guide bush attached to an inner circumference of the holder; and a scraper arranged at an end of the holder. The V-packing is formed of a thick-walled top portion, a thin-walled inner side skirt portion extending diagonally inward from the top portion, and a thin-walled outer side skirt portion extending diagonally outward from the top portion. The inner side skirt portion slidably contacts an outer surface of the rod at a distal end of the inner side skirt portion, and the outer side skirt portion abuts against an inner surface of the holder at a distal end of the outer side skirt portion. The top portion is sandwiched between the scraper and the first guide bush, and the inner and outer side skirt portions are freely deformable inside a space formed between the first guide bush and the scraper.
