Abstract
Swirl flow-forming body includes main body, first end face that is formed at main body and faces a member to which suction is applied, hole that opens on first end face, jetting port that is formed on inner periphery of main body, inner periphery facing hole, and fluid passage that allows fluid to be discharged into hole via jetting port so as to form a swirl flow that generates negative pressure for applying suction to the member. Inner periphery is formed so as to guide fluid discharged via jetting port, in a direction away from the member, to be discharged from hole.
