How to put spacing between the chapter and the text on the summary ?

Hi Guys,
i’m trying in many ways to do so, but i never get it.
All my generated lines of the summary are without space between the chapter number and the text.
How it works ?

Thx u all!

What kind of “summary”?

Is it a “Table of Contents”?

If so, please have a look at modification of contents style.
