Provided is a toilet seat structure for an aircraft lavatory unit. A toilet seat cushion block includes an inner and outer band-like bodies. The inner band-like body extends in a band-like shape at a section close to an inner circumference of a lower surface of a toilet seat, and the outer band-like body extends in a band-like shape at a section close to an outer circumference of the lower surface. Air communication passageways communicating with an inside and an outside of a bowl portion include: inner openings provided at an interval in the extension direction of the inner band-like body; an annular space between the inner and outer band-like bodies; and outer openings provided at an interval in the extension direction of the outer band-like body at sections of the outer band-like body, which are shifted from the inner openings in a circumferential direction of the toilet seat.

Provided is a toilet seat structure for an aircraft lavatory unit. A cushion block is formed of a single band-like body that has a band-like shape extending with a predetermined width along an entire circumference of a toilet seat in a circumferential direction. The band-like body has an elongated cross-sectional shape cut along with a plane orthogonal to the extension direction and includes: a flat upper surface; a flat lower surface; and inclined surfaces provided on both sides in the width direction. The band-like body has the upper surface that is attached to a lower surface of a body plate portion with an adhesive and inclined surfaces that form an obtuse angle with respect to the lower surface of the body plate portion.
