Kind Code:
B2
Abstract:
[Abstract] [Problem] To make a ball easy to be grabbed. [Solution] In a skin body 3 which covers a ball main body 2, a skin part 2 and a circumferential wall part 3 protruding from a peripheral edge part of the skin part 2 to a back side are integrally formed by molding of injecting a soft material made of resin or rubber into a mold. Alternatively, a structure is such that a step part or flat surface part where a finger is hung is provided on a front surface of the ball main body 2 or a front surface of the skin body 3 which covers the ball main body 2. Alternatively, a front surface of one of adjacent skin bodies 3 and a front surface of the other thereof configure a step part in a radial direction of a ball 1. With this, even in a ball game where the ball 1 is grabbed with hand such as a handball game, when a person grabs the ball 1, the skin part 4 of the skin body 2 is easily recessed, a finger is hung on the step part, or the flat surface part is touched with a finger to make the person feel that the ball 1 has a small outer diameter. With this, the ball 1 becomes easy to be grabbed, thereby making it easy to throw or catch the ball 1.
