Good too.

- The first holding part 42 and the second holding part 52 may be formed integrally with the case 11.
- In the above embodiment, the first terminal cover 12 and the second terminal cover 13 each hold one terminal, but in addition to this, for example, at least one of the first terminal cover 12 and the second terminal cover 13 holds one terminal. However, it may be configured to hold a plurality of terminals.

- The number of terminal covers provided in the electrical connection box 10 is not limited to two as in the above embodiment, and may be configured to include three or more terminal covers.
The technical ideas that can be understood from the above embodiment and modification examples will be described.

(a) The case has a first locking portion that locks on the first terminal cover, and a second locking portion that locks on the second terminal cover,
The first terminal cover and the second terminal cover are assembled to the case in the same direction,
When viewed from the assembly direction of the first terminal cover and the second terminal cover, the first locking part and the second locking part are located between the first holding part and the second holding part. are doing.

According to this configuration, the first locking part and the second locking part are located between the first holding part and the second holding part when viewed from the direction in which the first terminal cover and the second terminal cover are assembled. . Therefore, the dead space that may occur between the first holding part and the second holding part can be utilized more effectively.
