Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an attachment structure for a faucet, and more particularly to an attachment structure for attaching a water discharge pipe or a faucet body to an attachment base such as a counter via a pedestal formed separately.
[0002]
BACKGROUND OF THE INVENTION
2. Description of the Related Art Conventionally, there has been known a faucet mounting structure in which a water discharge pipe or a faucet body is mounted on a mounting base such as a counter in a sitting state via a base.
By the way, as a kind of faucet, an operation rod for remotely operating a drain plug provided in the lower part of a water tank such as a wash basin or a bathtub, and a cylindrical shape through which the operation rod is movably inserted to form an operation guide A water faucet equipped with a rod guide is used.
[0003]
For example, Patent Literature 1 and Patent Literature 2 below disclose a faucet provided with such an operating rod in a form that penetrates the faucet body.
Conventionally, a water discharge pipe or a faucet body (specifically, its shell) is formed of a metal casting (casting). In this case, the water discharge pipe or the faucet body (hereinafter referred to as a water discharge pipe) is a pedestal. And the rod guide can be formed integrally.
[0004]
However, casting water discharge pipes inevitably have a high price, and it has been considered that the water discharge pipes are formed by processing bar materials or pipe materials.
In this way, the water discharge pipe can be manufactured at low cost.
[0005]
However, when the water discharge pipe is constructed by processing a bar or pipe material, the pedestal must normally be configured separately from the water discharge pipe. In such a case, the water discharge pipe is countered via the pedestal. When mounted on an equally mounted base in a seated state, the water discharge pipe can rotate relative to the pedestal, which causes a problem that the fixing strength in the rotation direction of the water discharge pipe is weakened.
Although the case of the water discharge pipe has been described above, a common problem occurs when the faucet body is similarly formed by processing a bar or pipe material.
