Abstract
The present invention provides a gland packing in which a phenomenon where reinforcing fibers protruding from ends of adjacent braiding yarns overlap with each other, and the over-lapping reinforcing fibers are interposed over the whole range between expanded graphite tapes of the adjacent braiding yarns to form a leakage path can be reduced. In the gland packing , ends in the width direction of each of the braiding yarns A to H constituting the gland packing are directed to the inner side in the width direction, and the reinforcing fibers A to H protruding from the ends are confined to the inner side of the braiding yarns A to H.
