A new baseball glove is hard and difficult to open and close, and is likely to cause a catching error. Therefore, the baseball glove is typed into a mold that allows the user to catch the ball most easily.
For example, the baseball glove can be shaped by softening the skin by applying oil or squeezing, and the tip of the thumb insertion part and the little finger insertion part of the glove body are close to each other. In order to obtain a shape, the main and small finger bases of the glove body are struck repeatedly with a mallet etc. to make a crease, and the catching surface of the glove body is struck with a mallet again and again. The catching surface is made into a wide pocket by stretching the skin.

However, in the above-mentioned baseball glove, in the glove body, the region extending from the tip side of the thumb insertion part to the part corresponding to the mother and child sphere of the hand, and the part corresponding to the little finger ball of the hand from the tip side of the little finger insertion part. Since the entire region is reinforced hard, it is difficult to mold into a mold that is easy for a user to catch a ball when there is little experience in glove mold making.
In particular, when used by children, since the hand is small, it is difficult to mold to an optimal bending site, making it difficult to mold, and it has become a glove that is difficult to catch.

  The present invention has been made in view of the above-mentioned actual situation, and the main problem is that even if there is little experience in making a glove mold, it can be easily molded into a mold that is easy for a user to catch a ball. It is also possible to provide a baseball glove that can be used immediately after purchase without being molded.

  The first characteristic configuration of the baseball glove according to the present invention is that the MP joint of the thumb inserted in the thumb insertion portion of the glove body provided with a finger bag inside the glove-shaped outer skin having a catching surface.
