why the aperture changes for each shot when I use exposure bracketing

Hi..when I use exposure bracketing 3images, the aperture changes for each of the shot.
for example 0.5s f10 ,1/4s f14, 1s f7.1
I only want change shutter speed..do not want change aperture...
and I do not see any setting related to this issue

Bracket in Av mode and it wont change. I recall this happening to me in TAv mode, and it will definitly happen in Tv mode.

You can play with the program line setting; might do the trick in M mode

Just a heads up (in case you don't set a custom or preset white balance or set it in post when you shoot in RAW), the white balance will also change (within the brackets) if you use auto bracketing. So if you use auto bracketing, keep an eye on the white balance values/temperatures on the individual exposures. Of course this only really applies if you are using different exposures together or are making a HDR of the exposures.
