In the accommodation space 4, a weight adjusting member 5 having a weight different from the weight of the chopstick material corresponding to the volume of the accommodation space 4 is accommodated.

  Specifically, the weight adjusting member 5 is set to be heavier than the weight of the chopstick material corresponding to the volume of the accommodation space 4. That is, the weight adjusting member 5 functions as a weight of the chopsticks 1. In the illustrated embodiment, the weight adjusting member 5 is accommodated in the accommodating space 4 over the entire accommodating space 4 to compensate for insufficient strength of the chopstick body 2 due to the provision of the accommodating space 4. It also functions as a reinforcing member.

  Specifically, the chopstick body 2 is made of cedar or cypress, which is a relatively light material, as a chopstick material belonging to wood or bamboo. The chopstick body 2 is divided into upper and lower parts, and includes a first divided body 2a on the chopstick tip 3 side (lower side) and a second divided body 2b on the chopstick head 6 side (upper side). Specifically, the chopstick body 2 has a fulcrum portion of the chopstick 1 (a portion where the fingertip side of the thumb hits when the chopstick 1 is held), that is, the length of the chopstick 1 (chopstick body 2) on the chopstick head 6 side. It is divided up and down at a position approximately 1/3 from the end. The accommodation spaces 4 are provided on both sides of the divided surface 2 c of the chopstick body 2. That is, the storage space 4 is opened from the split surface 2c, the first storage space 4a on the chopstick tip 3 side (that is, the first split body 2a) and the chopstick head 6 side (that is, the second split body 2b). ) Of the second storage space 4b.

  The weight adjusting member 5 is made of metal, for example. The weight adjusting member 5 is formed in a rod shape and is inserted into each of the first accommodation space 4a and the second accommodation space 4b from the division surfaces 2c of the first division body 2a and the second division body 2b. Is done. That is, the weight adjusting member 5 is inserted so as to straddle the first accommodation space 4a and the second accommodation space 4b. And after insertion, the 1st division body 2a and the 2nd division body 2b are mutually adhere | attached and connected in the division surface 2c, for example.

  The chopsticks 1 are painted so that the base of the chopstick body 2 can be seen from the outside. For this coating, natural paints such as lacquer, beeswax, strawberries, shellac, vegetable dry oil, or other paints such as synthetic resin paints can be used. In the coating, generally, the finishing coating is performed after the sealing coating is applied. However, only the sealing may be applied, and the coating method is not particularly limited.

  Next, the function and effect of the chopstick 1 having the above configuration will be described.

  According to the chopsticks 1, the chopstick body 2 has the weight adjustment member 5 accommodated in the accommodation space 4, so that the weight of the chopstick 1 can be set to a desired value by setting the weight of the weight adjustment member 5. The weight, particularly the weight that is easy to use, can be met, and it is possible to meet various needs for the weight of the user. The chopstick body 2 is made of chopstick material belonging to wood or bamboo, and the accommodation space 4 is closed and the accommodation space 4 is covered with the chopstick material, so that the accommodation space 4 or the accommodation space 4 is accommodated. The weight adjusting member 5 is in a state that the user cannot visually recognize. For this reason, the appearance of the chopsticks 1 does not change. That is, the housing space 4 is provided in the chopstick body 2, and the weight adjusting member 5 is housed in the housing space 4, so that the weight is not captured by the weight of the chopstick material and the appearance is not changed. It can be the weight (that is, the weight required by the user).

  In addition, since the base of the chopstick body 2 is painted from the outside, the user can predict the weight of the chopstick 1 when the base of the chopstick body 2 is noticed. On the other hand, when the chopstick 1 is held, it feels a weight different from the predicted weight (in the illustrated embodiment, the weight adjusting member 5 is a weight and feels heavier than the predicted weight. ) Can give the user surprise and fun.

  The chopstick body 2 is divided at the fulcrum part of the chopstick 1, and the weight adjusting member 5 is inserted into the first accommodation space 4a in the first divided body 2a and the second accommodation space 4b in the second divided body 2b. Therefore, the fluctuation of the center of gravity of the chopstick 1 due to the provision of the weight adjusting member 5 can be reduced. For this reason, the easiness of holding the chopsticks 1 is not impaired.

  FIG. 2 shows a second embodiment of the present invention.
