There are badminton, squash, rackets such as racket balls, baseball bats, golf clubs, etc., tools include hammers, and motorcycles include bicycles, motorcycles, etc. There is a fishing rod as an example. Such tools are from wood to metal,
Then, development proceeded to composite materials, and functions such as lightness and good flying were pursued. However, on the other hand, among various materials, the vibration absorption property is low, there is discomfort at the time of hitting due to residual vibration, especially the impact when removing the sweet spot is too severe, especially the elbow is hurt in tennis, When it became chronic, there was a problem of becoming a tennis elbow. The impact is so strong that even a baseball bat cannot be grasped, and other problems such as tools and motorcycle handles are also seen.

の音が変わる程度のものにすぎなかった。For the purpose of reducing and mitigating impact vibrations at the time of hitting a ball,
For example, in the case of a tennis racket, a "stabilizer" has been proposed and put on the market. This is to attach a rubber or hard synthetic resin product to the gut of the racket and has a function of suppressing the vibration of the gut itself. However. this is,
Since the vibration from the frame of the racket is not suppressed, there is no function to mitigate the shock vibration transmitted to the grip, it was just a change in the sound of the gut.

In Japanese Unexamined Patent Publication No. 1-288279, a small hole is formed near the grip portion of the racket frame. It is disclosed that a weight is provided inside the hole via a gel layer.

があった。However, the former attempts to transmit the vibration of the main body by a fine linear elastic string and to link the weight with the elastic string, but it is difficult to adjust the relationship between the weight and the elastic string. There was a problem that it was not possible to achieve a sufficient effect.

Since it vibrates only by force, there is a problem that shock vibration cannot be absorbed stably in the end.

な鉛が好ましい。The weight of the present invention may be any weight that can be used as a weight of lead, iron, copper, ceramics, etc.,
It is not particularly limited, but since the mounting portion has a limited volume, it is desirable to use lead that is as heavy as possible, preferably has a specific gravity of 7 or more, and is easily available and inexpensive.

にもなるので好ましくない。The weight of the present invention depends on its volume,
The total weight is preferably at least 1 g, more preferably 3 to 20 g, but if the weight is too light, the vibration damping performance will be reduced. In addition, if the weight is too heavy, it is against the recent tendency toward weight reduction of sports equipment, and the overall weight balance is impaired, which is not preferable.

A member that develops three-dimensional elasticity is preferable, and for example, a foamed elastic body, a projecting elastic body or a combination structure thereof is preferable because it has an excellent function of exciting shock vibration.

成を採用するのが好ましい。The elastic body can be used properly depending on the magnitude of the impact force. For badminton and table tennis, which have a comparatively small impact force, the foamed elastic body alone can exert its sufficient effect, and for tennis balls, squash, golf clubs, etc., which have a moderate impact force, foam and protrusions. The double structure of the seat, or the one having a large impact force such as baseball, is preferably the projection alone. However, even if such an elastic body has a large impact force, the weight bottoms out and the effect disappears. In that case, protect the projection elastic body without bottom projection or use the projection elastic body on the entire surface. It is preferable to adopt the configuration of.

Those having a performance of about 0.5 to 200 kg / cm 2 at a stress at 0% elongation are preferable, and the shape of the protrusion made of the elastic body is various shapes such as a cylinder, a prism, a cone, and a pyramid. For example, in the case of a cylinder, the diameter is 0.5 to 5 mm and the height of the protrusion is 0.5 to 10 mm.
The size of the member is determined based on the volume restrictions of the member mounting location. In addition, the density of the projections is such that the area occupation rate of the projections is 5 to 5.
The range of 80% is preferable. If it is 5% or less, the elastic force is insufficient and the weight holding property is deteriorated. If it is 80% or more, the elasticity becomes too high, the movement of the weight is restricted, and the vibration absorbing effect is reduced. In the case of a quadrangular pyramid, one side may be 100%, and if the apex can hold the weight, it can be used with an appropriate size.
