  According to this configuration, not only the first slope body and the second slope body are relatively moved in the vertical direction, but the first slope body is not rotated unless the first slope body is rotated with respect to the second slope body. And the connection of the second slope body is not released. Therefore, according to such a configuration, the slope is more difficult to come off from the gate.

  In the slope, the upper surface engaging portion and the upper surface engaged portion have the same shape, and the lower surface engaging portion and the lower surface engaged portion have the same shape, The upper surface engaging portion and the lower surface engaging portion are arranged symmetrically with respect to the center in the width direction of the first slope body, and the upper surface engaged portion and the lower surface engaged portion are arranged on the second slope body. You may arrange | position symmetrically on the basis of the width direction center.

  According to such a configuration, the first slope body and the second slope body can have the same shape. Therefore, it is not necessary to manufacture the first slope body and the second slope body separately, and the manufacturing cost of the slope can be suppressed.

  In the above slope, the engaging surface or the engaged surface may have side wall portions at both ends in the width direction.

  According to this structure, the movement of the width direction with respect to the to-be-inserted part of an insertion part is controlled by the side wall part. Therefore, the first slope body does not shift in the width direction with respect to the second slope body, and the slope can be firmly attached to the gate.

  As described above, the gate slope can be firmly attached to gates having different shapes and sizes.
