I like biking but I have very limited knowledge in bikes.

I need a front suspension forks for one of my bike. I saw a post selling one which I would like to buy. But from its photos, I found that there is a place that it is different from the front suspension forks of my other bikes. The difference is the angle of the drop out. (I may used the wrong term, but I do not know the proper term for it). Actually, I mean the angle of the slot (drop out) going into the axle of the front wheel. Mine are parallel to the vertical line of the forks, but the one for sale is at an angle. Sorry, I cannot post the photos because I am just a new member. I am trying to find a way to post the photos somewhere else.

It seems to me that it is not that good because the front wheel may have a higher chance of coming out. Am I correct? Or am I just ignorance?

There should still be a recessed lip around the axle nuts to prevent a loose wheel from leaving the scene. (Remember the hit song, "You picked a fine time to leave me, loose wheel?")

Perhaps the dropout slots are perpendicular to the ground when installed in a standard angled head tube.

There is a legal requirement that bikes have some method of holding in a loosened wheel. The lips mentioned above are often referred to as "lawyer lips."

Thank you for your reply.

Some disc brake-ready forks for traditional quick-release hubs have the dropout slot angled forward in an attempt to reduce the risk of the front wheel ejecting when the disc brake is applied.
Other makes&models are content with relying on the ”lawyer lips” and operator skill/strength to keep the front wheel in place. They may well hang on to a more traditional, near-vertical angled dropout
