Abstract: An object hardness measuring device includes a first side portion, a second side portion, a pedestal unit, a load unit, a measuring unit, and a holding unit. The load unit applies a load to the measurement object. The measuring unit is able to measure, in a state where the load acts on the measurement object, at least one of a movement distance of the second side portion with respect to the first side portion and a change amount of the load when the second side portion is moved either at a predetermined speed or to a predetermined position. The holding unit is able to hold the measurement object, and is movable between the first side portion and the second side portion by the slide rail unit.

As a result, there can be obtained a baseball that achieves a high level of safety when the baseball hits against a human body and achieves a hit distance equal to and longer than that of a ball for hardball.

Abstract: A baseball includes an inner core, and an outer layer covering the outer circumferential surface of the inner core. The inner core has a surface hardness of not less than 60 and not more than 80 in Asker C hardness, and has an elastic modulus of not less than 0.6 MPa and not more than 1.0 MPa. In this way, a baseball can be obtained which can achieve a trajectory comparable to that of a ball for hardball after hitting and which can achieve an impact force comparable to a ball for rubber-ball baseball.

The palmar side comprises a plurality of detached finger pads adapted to limit shock to a batter's hand encountered during batting. The plurality of detached finger pads comprise a palm pad configured to cover a lower portion of a palm of the hand, a first finger pad configured to cover a metacarpal of a pinky finger, a second finger pad configured to cover a metacarpal and a phalange of a ring finger, a third finger pad configured to cover a metacarpal, a proximal phalange, and an intermediate phalange of a middle finger, and a fourth finger pad configured to cover an area between a thumb and an index finger. Other aspects, embodiments, and features are also claimed and discussed.

Abstract: Disclosed is a catching tool for baseball or softball including a ball receiving portion covering the palm side of a user's hand when wearing the tool and containing a ball receiving surface for receiving a ball, a resin layer that is selectively formed on the surface of the ball receiving portion and can be deformed along a surface of the ball when catching the ball, and a back portion for covering the back of the user's hand. On the ball receiving portion, various resin layers may be optionally formed, examples of the resin layers including a large-width resin layer, and a small-width resin layer having a convex regions.

Abstract: 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

Abstract: A glove wearable for exercise includes a back part covering the back side of a wearer's hand when worn, a palm part covering the palm side of the wearer when worn, and a resin pattern formed tightly adhered on a surface of the back part. The resin pattern is formed in a web, and density of the pattern is preferably adjusted region by region of the back part, in accordance with the amount of deformation when the glove is worn.

Abstract: 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 (2a to 2e) on anterior and posterior sides of the same, and arranging stretchable members (4a to 6a) 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.
