At this time, the antenna 32 may be mounted so as to be placed on the connection portion 28 or may be mounted so as to hang from the holding body 92. Thereby, since the antenna 32 is protected by the support | pillar 94, it can prevent that the antenna 32 is damaged or dirt, such as dirt, adheres, and communication failure arises. Further, since the solar cell unit 14 can be attached to and detached from the actuator main body 12, the antenna 32 and the solar cell unit 14 are separately placed in a place with good radio wave conditions according to the situation of the field 102 such as the presence or absence of an obstacle. it can. That is, since the installation position of the antenna 32 can be changed, communication can be ensured appropriately.

  The antenna 32 can also be disposed inside the holding body 92, for example, in the frame 92a or in the attachment portion 92c. Also by this, the same effect as the arrangement of the antenna 32 in the column 94 can be obtained.

  In this embodiment, a motor with an encoder is used as the motor 38. The encoder of the motor 38 outputs a pulse signal corresponding to the rotation direction and the rotation speed of the output shaft 38a to the CPU of the control unit. The CPU of the control unit calculates the position of the valve body 130 of the water supply device 104 or the partition body 142 of the drainage device 106 based on the pulse signal input from the encoder, that is, the rotation direction and the rotation speed of the output shaft 38a. That is, the encoder is used as a position detection unit that detects the position of the valve body 130 or the partition body 142. However, the encoder that functions as the position detection unit is not necessarily provided in the motor 38. The encoder is provided in the main gear 40, and the valve body 130 or the partition body 142 is determined based on the rotation direction and the rotation speed of the main gear 40.

Moreover, the direction of the solar cell panel 90 can be set to an arbitrary direction. Therefore, it is possible to flexibly cope with the situation of the farm field 102 where there is an obstacle or the like, and it is possible to secure good solar radiation of the solar cell panel 90.

  Further, since the length adjustment column 98 can be added to the column 94, the installation height of the solar cell panel 90 can be arbitrarily set. Therefore, the situation of the field 102 can be dealt with more flexibly, and good solar radiation of the solar cell panel 90 can be secured.
