クラス自体（これはすでに callable です）ではなく、そのクラスのインスタンスです。

そのためには、`__call__` メソッドを宣言します:

{* ../../docs_src/dependencies/tutorial011_an_py310.py hl[12] *}

この場合、この `__call__` が、**FastAPI** が追加のパラメータやサブ依存関係を確認するために使うものになり、後であなたの *path operation 関数* のパラメータに値を渡すために呼び出されるものになります。

## インスタンスのパラメータ化 { #parameterize-the-instance }

そして、`__init__` を使って、依存関係を「パラメータ化」するために利用できるインスタンスのパラメータを宣言できます:

{* ../../docs_src/dependencies/tutorial011_an_py310.py hl[9] *}
