In FIG. 18, the solid line indicates one unit unit panel 120U, the thin line indicates another unit panel 120U (or the skin panel 121), and the alternate long and short dash line indicates the pentagonal portion PE.

The exercise ball 100 of the second embodiment shown in FIGS. 11 to 18 is substantially the same except that the skin layer 120 is different from the skin layer 20 of the exercise ball 1 of the first embodiment. Therefore, the epidermis layer 120 will be described, and the other parts will be omitted.

The skin layer 120 is configured by connecting a plurality of triangular skin panels 121, and is adhered to the cover rubber layer 12 with an adhesive.

The skin panel 121 has a triangular side of about 1 cm to about 4 cm, and is formed of natural leather, artificial leather, synthetic leather, or the like.

Further, in the triangular skin panel 121, a triangular pyramid-shaped recess (recess) 123 is formed on the main surface (see FIG. 18). The depth of the recess 123 is about 0.1 mm to 1.0 mm. A fine uneven pattern 22 (not shown) similar to that of the first embodiment may be formed on at least one of the slope or the bottom surface of the recess 123.

By the way, in the skin panel 121, for example, a plurality of skin panels 121 of about 2 to 25 are integrally molded via a dummy seam DS. In the second embodiment, the skin panel 121 has the same triangular skin panel 121 adjacent to each other in a triangular shape (1 for the 1st stage, 3 for the 2nd stage, 5 for the 3rd stage, and 4th for the 4th stage). By arranging 16 sheets in 7 sheets), one unit of triangular portion TR is formed.

Further, the triangular portion TR is integrally molded as a unit panel 120U. Further, by arranging five triangular portions TR (unit panel 120U) of one unit so as to share one vertex W, a pentagonal portion PE is formed, and four pentagonal portions PE form a spherical surface. The shape of the epidermis layer 120 is formed. In other words, the epidermis layer 120 is formed by 20 triangular portions TR. In other words, the skin layer 120 is formed of 320 triangular skin panels 121.

The triangular portion TR has three outer peripheral sides as seams S, seams 130 in the edge region of the seams S, and dummy seams DS between the inner skin panels 121, and edge regions on both sides of the dummy seams DS. Has a dummy seam portion 140. In other words, the pentagonal portion PE has the outer five sides as the seam S, has the seam portion 130 in the edge region of the seam S, and has the seam portions in the edge regions on both sides of the five seams S radially extending from the apex W. Has 130.

These seam portions 130 and dummy seam portions 140 have a larger diameter (inclined so as to increase in height) toward the seam S or dummy seam DS in a cross-sectional view orthogonal to the seam S or dummy seam DS. Actually, the seam S or the dummy seam DS may be centered in an inverted V shape (convex shape). A fine uneven pattern 22 similar to the main surface of the skin panel 21 may be formed on the apex surface and the inclined surface of the seam portion 130 and the dummy seam portion 140, or the seam S or the dummy seam DS. Fine uneven patterns 22 such as parallel or intersecting straight lines may be formed.

In the second embodiment, the pentagonal portion PE is formed by five triangular portions TR (unit panel 120U), but the triangular portion TR does not have 16 skin panels 121 arranged, for example. , 9 or 25 skin panels 121 may be arranged.

The skin layers 20 and 120 are configured by connecting a plurality of triangular skin panels 21 and 121 via seams S or dummy seams DS, and adjacent skin panels 21 so as to share one vertex V and W. , 121 have a pentagonal portion PE in which five sheets are arranged. As a result, since the epidermis layers 20 and 120 have at least one pentagonal portion PE, the seam S or the dummy seam DS is not connected in a straight line all around the diameter of the spherical surface. Therefore, the exercise balls 1,100 can be easily grasped by hand or easily caught by a finger, and when the exercise balls 1,100 rotate, the seam S, the dummy seam DS, or the seam portion 30, The extending direction of the 130 or the dummy seams 40, 140 and the rotation direction do not match, and the difference in flight resistance and rotation resistance (rotational unevenness) depending on the rotation direction of the exercise balls 1, 100 can be suppressed. No matter which direction the exercise balls 1, 100 are rotated, a substantially constant flight trajectory or rotational motion can be obtained. Further, since the skin layers 20 and 120 of the exercise balls 1, 100 are aggregates of triangles, there is a sense of unity and the design is excellent.

In the first and second embodiments, two or more adjacent skin panels 21, 121 are integrally molded. This eliminates the need to bond or bond the skin panels 21 and 121 one by one when covering the tube 10, and can improve work efficiency.

In the first embodiment, the skin panel 21 has a seam portion 30 or a dummy seam portion 40 whose diameter decreases toward the seam S or the dummy seam DS. As a result, the vicinity of the seam S or the dummy seam DS becomes a concave groove shape, which makes it easier to grasp by hand or to be easily caught by a finger.

In the second embodiment, the skin panel 121 has a seam portion 130 or a dummy seam portion 140 whose diameter increases toward the seam S or the dummy seam DS.
