- the convex-shaped part 5 is formed in hollow, the said deformation
- the coat layer 7 is hardly formed on the outer surface of the convex portion 5. For this reason, the coat layer 7 is not formed on the outer surface of the convex portion 5, or even if it is formed, the coat layer 7 is relatively thin. Therefore, when the object to be grasped is grasped, the convex portion 5 is accurately deformed. Easy and sufficient grip. Further, when the coat layer 7 is not formed on the outer surface of the convex portion 5, the object to be grasped and the convex portion 5 are in direct contact with each other, and the material (resin) constituting the convex portion 5 and the material to be covered are covered.

- the convex part since the convex part is firmly fixed to the glove body, the convex part is unlikely to be detached from the anti-slip glove, so that the grip force is not easily lowered even when used for a long time.
- the convex portion 5 faces one end side of the fabric of the glove body 3 when the object to be gripped is gripped. While pulling up to the side, it is possible to regulate the movement of the root portion escaping from the palm of the wearer. That is, when the convex portion 5 is simply provided on the glove body 3 without providing the coat layer 7, a force is applied to the convex portion 5 in the palm plane direction (for example, fingertip direction) when the object to be grasped is gripped.
- the palm plane direction for example, fingertip direction
- the convex part 5 will pull the one end side (sleeve side) part of the glove body 3 to be fixed to the outer surface side and the base part of the convex part 5 will move away from the palm. The force may not work.
