2. Description of the Related Art Various cabinets are known in which equipment can be stored and taken out. For example, what is arranged under the sink of a sink or what is called a wall cabinet attached to the upper part of the wall of the kitchen is exemplified. Most of these cabinets are factory-finished products, and at the construction site, they can be mounted with pedestals, doors, shelves, and installed in predetermined parts.

Specifically, as shown in FIG. 9 and FIG. 10, a conventional cabinet has a left side plate (1), a right side plate (2), a main plate (3), a back plate (4) and an upper plate. It is said to be a factory finished product in which the member (5) is assembled. In this example,
As the upper member (5), two members, an upper front crosspiece (5a) and an upper rear crosspiece (5b), are employed, which are spaced apart from each other at the front and rear ends of the cabinet upper end, and a sink or the like is arranged between them. Is possible. In addition to this, a single top plate may be used for the upper member (5). There are several modes for the upper member (5) depending on the type of cabinet, application, and the like.

In such a cabinet, as shown in FIG. 9 and FIG. 10, the back plate (4) generally does not use a fixing tool (6) such as a screw or a dowel, but the left side plate (1), The right side plate (2), the base plate (3) and the upper member (5) are sandwiched and fixed. That is,
A vertical groove extending the entire length in the vertical direction is formed at the rear ends of the left and right side plates (1) and (2), and the rear ends of the main plate (3) and the upper member (5) (in this example, the upper rear crosspiece (5b)). A lateral groove extending over the entire lateral length is formed in the portion, and the four circumferential ends of the back plate (4) are fitted into these vertical grooves and lateral grooves to form a left side plate (1), a right side plate (2), and a main plate (3). The upper member (5) and the upper member (5) are joined by the fixtures (6) at the portions where they abut against other members.

One of the reasons for adopting such an assembling method is to give the cabinet sufficient strength against a force applied in the vertical direction, that is, a compression force. Also, the cabinet is a factory finished product,
The left side plate (1), the right side plate (2), the main plate (3) while maintaining the state of fitting in the longitudinal grooves and the lateral grooves of the four peripheral ends of the back plate (4).

Depending on the installation location, piping and wiring may be pulled inside. The piping, wiring, etc. are drawn in through the back plate (4) in consideration of exposure and the like, and an opening is formed at a predetermined position in the back plate (4). Since the position of the opening is determined by the position of the piping, wiring, etc. to be drawn in,
Usually, the work for making holes in the back plate (4) is a work at the construction site. Cabinet back panel (4) that is a factory finished product
When making a hole in the cabinet, the only way to make a hole with a good quality finish is to have the builder work inside the assembled cabinet. Therefore, the opening of the back plate (4) is difficult and time-consuming.

On the other hand, some of the cabinets have preformed holes in the back plate (4) in anticipation of such inconvenience, but it goes without saying that the positions of the holes are all set in the construction. Often, there is no need to correspond to the site, and in the end, it is often necessary to form an opening at another position.

The invention of this application has been made in view of the above circumstances, and enables assembly at a construction site rather than a factory-finished product.
It is an object to be solved to provide a cabinet that can easily form an opening for wiring and the like and a method for constructing a back plate thereof.
