Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pair of right and left, which are used by producing a metallic rubbing sound by rotating and rubbing as a percussion instrument at a ritual such as Buddhism, such as Nichiren Buddhism and Hokke Buddhism. Regarding the improvement of the pot.

[0002]

2. Description of the Related Art Normally, a genius bowl used in Buddhist memorial services is used as a percussion instrument which strikes a pair of left and right dish-shaped genius bowls like a cymbal to generate a percussion sound.

However, in the case of a ritual such as the Buddhist memorial service in the Nichiren sect of Buddhism, the pair of right and left dish-shaped bowls are not slapped, but they are rotated by the wrist, palm and fingertips, and rubbed against each other. It is used to generate sound, and its rotating operation is extremely difficult, and unless a monk with an extremely high level of skill, it is difficult to generate the desired rotational rubbing noise and the atmosphere of the solemn ritual is markedly marked. Often damages.

The factor of the difficulty exists in the rotating structure of the Myochi bowl. In the old days, a shaft string was passed through the eyelet provided in the center of the Myochi bowl.
Attach a drop-out prevention member such as a ball to the end of the axle string that protrudes inside the Myoko, and form it on the back plate of the back of the hand that is inserted into the axle that protrudes outside the Myoko and the outside of the center of the Myoko. Insert your hand between it and a bowl-shaped palm abutment protrusion, grasp the palm abutment with tension applied to the axel, and rotate the palm to use the axel as a rotation spindle to make a sword. It is well known that the Myochi bowl is designed to rotate.

In addition, relatively recently, JP-A-10-24
As disclosed in Japanese Patent Publication No. 7082, in the inside of the bowl-shaped palm abutment protrusion of the tatara bowl, two receiving members are interposed on the shaft cord, and between the two receiving members. In addition, two washers of the thrust bearing are interposed, a thrust bearing is interposed between the two washers, and a series of annular members formed by the receiving member, the washer, the thrust bearing, the washer, and the receiving member. It is also known that the rotating structure of the Myochi bowl is configured by passing the axial cord through the hole at the center of the row and providing the knot cancer of the axial cord at the inner end thereof.

[0006]

However, in the case of the former of the above-mentioned conventional techniques, the rotation supporting shaft of the sword bowl is a shaft string, and a bearing mechanism or the like for smoothly rotating the sword bowl is provided. Since it is not equipped at all, it is extremely difficult to rotate the Myochi bowl and it is difficult to rotate it smoothly.To rotate the Myosaka bowl, pull the axel string outside and apply tension, and It is said that it is necessary to perform a difficult operation of holding the protruding part of the palm-shaped palm abutting it with the palm and rotating the tatami bowl while keeping the balance, and that the shaft cord is easily rubbed and scraped at the periphery of the eyelet. There's a problem.

In the latter case of the above-mentioned conventional techniques, since the thrust bearing mechanism is arranged inside the strange bowl, there is an advantage that the gentle bowl can rotate smoothly as compared with the former case. In this case also, since the axis string is used for the rotation support shaft of the tatara bowl, in order to rotate the tatara bowl, it is necessary to pull the axis string outward and apply tension to rotate it.
There is a problem that it is difficult to completely prevent the shaft cord from being rubbed and cut at the periphery of the eyelet even with the skill of a skilled monk.

The present invention was developed with the object of solving the above-mentioned problems, and it is not necessary to apply tension to the rotary support shaft of a tatami bowl, and even a beginner can rotate the tatara bowl very smoothly and easily. It is an object of the present invention to provide a special bowl with the advantage that the rotary support shaft of the bowl body is not cut.
