CONTROL UNIT IN BOX SHAPE

PROBLEM TO BE SOLVED: To reliably seal a gap between a connector and a base which are assembled and to avoid the waste of sealing material.

SOLUTION: A pier 12 is provided on the peripheral wall 3 on a front side constituting the base 1 and a lower sealing groove 27 is formed in the underside of the connector 17 facing the base 1. When a circuit board 15 is fitted to the base 1, the end 12A of the pier 12 is fitted in the lower sealing groove 27 of the connector 17. In this way, since the gap formed between the peripheral wall 3 of the base 1 and the underside 20 of the connector 17 is minimized and can be reliably sealed by a small amount of sealing material 36, the waste of sealing material 36 can be avoided and this contributes to reduction in manufacturing costs.
