The attachment 100 according to the present embodiment includes a base 20 installed on the floor F, a support 30 erected at the rear end of the base 20, and a support provided on the top of the support 30 to support the television T. An additional support 110 that is attached to the support 30 and extends rearward from the support 30, and an additional support that is installed on the floor F and abuts the base 20 from the rear. The elongated hole 121e and screw 161 of the upright piece 121c that connects the additional support 110 and the additional base 120 by allowing relative movement of the additional support 110 and the additional base 120 in the vertical direction, and the rectangular convex portion 121c. Since the rectangular opening 135a and the rectangular opening 145a are provided, even if a strong force from the front acts on the TV stand 10 with the support 30 erected at the rear end of the base 20, the force will be applied to the additional support 110. This is transmitted to the floor F via the additional base 120 and can be resisted by the reaction force from the floor F, thereby preventing the TV stand 10 from falling.

On the other hand, when a force acts on the TV stand 10 from behind, if the additional support column 110 and the additional base 120 are not allowed to move relative to each other in the vertical direction and are rigidly fixed, the result will be as shown in FIG. 25(a). In addition, the additional base 120 tilts forward together with the additional support 110 fixed to the support 30 and floats off the floor surface F, and even when the force from behind ceases to act, it does not return sufficiently and remains in a floating state. However, in this case, the elongated hole 121e and the screw 161 that connect the additional support column 110 and the additional base 120 have a simple structure, but allow the relative movement of the additional support column 110 and the additional base 120 in the vertical direction. ), even if a force acts on the TV stand 10 from behind and the additional support 110 tilts forward, play in the elongated hole 121e and screw 161, rectangular convex portion 121c, rectangular opening 135a, and rectangular opening 145a will be reduced. Due to the non-fixation, the additional base 120 does not follow, and it is possible to prevent the additional base 120 from rising from the floor surface F (the lifting caused by the displacement or deformation of the additional base 120 with respect to the base 20 as shown in FIG. 2(a)).

Furthermore, since the attachment 100 is provided with a rectangular convex portion 121c, a rectangular opening 135a, and a rectangular opening 145a that restrict the relative movement of the additional support column 110 and the additional base 120 in the lateral direction, for example, an external force acts on the additional support column 110. Even if the additional support column 110 and the additional base 120 are lifted off the additional base 120, the additional support column 110 and the additional base 120 are prevented from shifting in the lateral direction (front, rear, left and right directions).

Although the embodiments of the present invention have been illustrated above, the embodiments of the present invention are not limited to those described above, and may be modified as appropriate without departing from the spirit of the invention.

For example, in the above embodiment, the shaft portion (screw 161) provided on the additional support 110 side and the long hole (long hole 121e) provided on the additional base 120 side allow the additional support 110 and the additional base 120 to be vertically relative to each other. Although a connecting portion is configured to allow movement and connect the two, a long hole may be provided on the additional support column 110 side and a shaft portion may be provided on the additional base 120 side, or the connecting portion may be formed using something other than the shaft portion and the long hole. may be configured. Alternatively, the relative movement of the additional column 110 and the additional base 120 in the vertical direction is permitted exclusively by the rectangular convex portion 121c, the rectangular opening 135a, and the rectangular opening 145a, and the elongated hole is formed into a circular shape that does not allow vertical movement of the shaft portion. It may also be a hole etc.

Further, the restriction portion that allows the relative movement of the additional support column 110 and the additional base 120 in the vertical direction and restricts the relative movement in the lateral direction may be formed of a structure other than a rectangular convex portion and a rectangular opening, and may be configured to cover the support base. The support may be a cleaner or the like other than the television.
