In the present invention, if the rib guide groove 8 is aligned with the rib 7 of the fitting cylinder 3 of the electrical junction box 1 and the mounting part 5 of the relay box 4 is inserted, the locking pawl 3a and the locking groove 5b (see FIG. As before, both of them are locked by engagement with (see).

なる。 If the relay is fitted into the relay box 4 in the inserted and locked state of the fitting tube 3 and the mounting part 5 shown in FIGS. 2a and 2b, the locking pawl 3
The rotational torque F' with the rotation center at part a acts as before. At that time, since the front end of the attachment part 5 is open, the side wall part 5 of the arm length part
Rotational torque is concentrated at c and 5c'. As a result, as shown in FIGS. 2a and 2b, the side wall portion 5 is opened at the front end.
c and 5c' are bent to expand, and since the rib 7 is rounded, when a force exceeding a predetermined rotational torque is applied, the rib 7 and the rib guide groove 8 are disengaged, and the mounting portion 5 comes off from the fitting tube 3. That is,
The holding force of the relay box 4 against the fitting tube 3 can be adjusted by adjusting the arm length. Therefore,
If R is made small, the arm length will be shortened, the side wall portions 5c and 5c' will be less likely to bend, and the holding force will be increased.
