【００３９】請求項３によると、嵌合溝を斜めに傾斜さ
せているので、透明基板を両側部嵌合溝に嵌合する際、
透明基板の湾曲方向が自ずから決まり、挿入時にその都

板の湾曲方向の乱れを防止できる。したがって、隣り合
う透明基板の隙間を一定に確保でき、洗浄効率を一定水
準に維持できるといった優れた効果がある。According to the third aspect, since the fitting groove is inclined, when the transparent substrate is fitted in the fitting grooves on both sides,
The bending direction of the transparent substrate is determined by itself, and not only the time and effort for adjusting the bending direction each time when inserting but also the disturbance of the bending direction of the transparent substrate can be prevented. Therefore, there is an excellent effect that the gap between the adjacent transparent substrates can be kept constant and the cleaning efficiency can be maintained at a constant level.
