Patent abstract
The present invention provides a gland packing in which impairment of the sealing performance due to cracks that unwillingly occur in an end portion in the width direction of an expanded graphite tape of a braiding yarn in the gland packing can be suppressed. In gland packings 1, 2, braiding yarns include braiding yarns 10A in each of which an expanded graphite tape 30 is bent so as to contract in the width direction, and both end portions 31 in the width direction of the bent expanded graphite tape 30 are folded back, or braiding yarns 20A in each of which at least an outer end portion 31′ in the width direction of a twisted expanded graphite tape 30 is folded back.
