the guide mechanism includes a pair of guide wall parts that are erected at positions sandwiching the tip-side claw part along the axial direction in the tip-side wall part for guiding the tip-side hook part toward the tip-side claw part along the rotation direction, and

in the tip-side locking mechanism, the tip-side hook part interferes with the pair of guide wall parts in a case where the tip-side hook part is displaced with respect to the tip-side claw part in the axial direction when the first cover member and the second cover member are combined by being rotated along the rotation direction.

4 . The terminal cover according to claim 2 , wherein

the guide mechanism includes a pair of guide wall parts that are erected at positions sandwiching the tip-side claw part along the axial direction in the tip-side wall part for guiding the tip-side hook part toward the tip-side claw part along the rotation direction, and

in the tip-side locking mechanism, the tip-side hook part interferes with the pair of guide wall parts in a case where the tip-side hook part is displaced with respect to the tip-side claw part in the axial direction when the first cover member and the second cover member are combined by being rotated along the rotation direction.
