In FIG. 1, 14 is an underwater shower nozzle, and 15 is an upper substrate guide.

The above construction is basically the same as that of the conventional example shown in FIG.

In this embodiment, the substrates to be conveyed move around on the net conveyor 3 in a direction other than the driving direction due to various treatments such as ultrasonic waves and showers, the substrates collide with each other and are damaged, and further, they are even. In order to prevent such troubles that it cannot be washed, it is configured as follows.

That is, the shaft 16 constituting the net conveyor 3 is provided with a restricting member 17 for restricting the movement of the substrate in the width direction of the net conveyor 3, as shown in FIG. That is, the restriction means is configured by being slidably displaced in the width direction of the net conveyor 3, and the ultrasonic cleaning device 1 is further configured.
At the lower position on the substrate loading side of the
An adjusting mechanism 18 is provided for adjusting the mounting position of each regulating member 17, that is, the position for regulating the transported object according to the transport operation of the net conveyor 3.

FIG. 2 is an enlarged perspective view showing the vicinity of the adjusting mechanism 18.

The net conveyor 3 is composed of a plurality of shafts 16 each having a fixed length, and both ends of the shafts 16 are connected to each other with a fixed interval between them so as to form an endless shape. A fixed guide 19 is attached so that the substrate to be conveyed does not run off the net conveyor 3 and fall or be damaged. Such a configuration is the same as the conventional one.

In this embodiment, a fixed guide as in the prior art is not provided at the other end of the shaft 16 which constitutes the net conveyor 3, but instead, as described above, the net conveyor 3 is not installed. Then, the regulation member 17 for regulating the movement of the board along the width direction of the net conveyor 3 is
