A glove of the present invention includes a stretchable member and protective members arranged on a side corresponding to a back of a hand, and when the glove is placed in a stationary state and viewed from the back side, the stretchable member forms two or more separate curve surfaces, and upper end portions thereof are located somewhere in lower half parts of finger covering parts, each of the curve surfaces formed with the stretchable member extends toward a wrist part, crossing a center line of at least one finger covering part selected from a second finger (forefinger) covering part, a third finger (middle finger) covering part, a fourth finger (ring finger) covering part, and a fifth finger (little finger) covering part, at least twice in a region from the upper end portions to a normal to the center line of the third finger (middle finger) covering part that passes an interdigit part between the first finger (thumb) covering part and the second finger (forefinger) covering part, and in regions between the curve surfaces of the stretchable member, the protective members are provided. This configuration makes it possible to provide a glove that is capable of following changes in shape caused by a gripping action of the hand, providing both of the feeling of fitting and the feeling of support, and having a high-level protection function and a high-level mobility function.

Glove

In a glove having finger covering parts, a finger covering part corresponding to at least one finger selected from the third finger (middle finger), the fourth finger (ring finger), and the fifth finger (little finger) is configured by arranging protective members (to) on anterior and posterior sides of the same, and arranging stretchable members (to) on both lateral sides of the same. An inner perimeter of each finger covering part is substantially equal to an outer perimeter of the finger corresponding thereto. The stretchable members on the lateral sides of each finger have stretching forces such that a stretching force of the stretchable member on the lateral side on the first finger (thumb) side is higher than a stretching force of the stretchable member on the other lateral side on the fifth finger (little finger) side. When the glove is bent from an opened state to a gripping state, the finger covering part is bent with a twist at a gripping angle toward the first finger (thumb) side. Thus, a glove is provided that is capable of following changes in shape caused by a gripping action of a hand, providing both of the feeling of fitting and the feeling of support, and having a high-level protection function and a high-level of mobility function.

An athletic glove comprises a back portion and a palm portion. A tape is stitched to the back portion. The tape extends from a little finger portion, a ring finger portion and a middle finger portion toward the base of a thumb portion, and can supply proper fastening force to the little finger, the ring finger and the middle finger of the user's hand when the user grasps an object.
