PROBLEM TO BE SOLVED: To suppress breakage of an engagement projection part formed on an inner cylindrical body.SOLUTION: A non-pneumatic tire 1 comprises: an attachment body 11 attached to an axle; a ring member 14 having an inner cylindrical body 12 which is provided on an outer part of the attachment body 11 and an outer cylindrical body 13 surrounding the inner cylindrical body from outside of a tire radial direction; and plural connection members 15 which are disposed between the inner cylindrical body and the outer cylindrical body in the tire peripheral direction and connecting the cylindrical bodies with each other. On an inner peripheral surface of the inner cylindrical body, an engagement projection part 35 projecting inward of the tire radial direction is formed. On an outer peripheral surface of the attachment body, an engagement recess 36 to which the engagement projection part is fitted is formed. Size of the tire peripheral direction on the engagement projection part gradually becomes smaller as goes to inside from outside of the tire radial direction. |
