In addition, guides 57 and 59 and seating portions 58 are formed on the left and right inner surfaces of the body portion 56 to facilitate the arrangement of the

boards

20, 30 and 40.

That is, in FIG. 3, a guide 57 into which the right end of the main board 20 is fitted is formed in the lower portion of the right inner side of the body portion 56 in the longitudinal direction. In other words, the fitting groove 57a is formed in the guide 57 in the longitudinal direction, and the right end of the main board 20 is fitted into the fitting groove 57a in a sliding form.

It is possible to fix. In addition, since the DSRC / WAVE module of the V2X board 30 will be connected to the

DSRC antennas

41 and 42 of the antenna board 40, the shaking of the V2X board 30 will be minimized.

In addition, the coupling portion 63 is formed in the longitudinal direction on the inner side of the rear cover 60.

The fitting groove 63a is formed in the longitudinal direction at the center of the coupling portion 63, and the rear end of the antenna board 40 is fitted into the fitting groove 63a.
