Top toy

A toy top comprising

• a shaft unit extending along an axis in an axial direction;
• a lower rotator and an upper rotator being configured over the lower rotator in the axial direction, the lower rotator and the upper rotator being relatively rotatable about the axial direction, the shaft unit being attached to the lower and upper rotators,
• the lower rotator including a first coupling piece including a lower surface,
• the upper rotator including a second coupling piece including an upper surface,
• the lower rotator and the upper rotator being relatively rotatable between a first relative rotation position and a second relative rotation position about the axis,
• the lower rotator configured to be coupled with the upper rotator at the second relative rotation position with the lower surface and the upper surface coming into contact,
• the lower rotator and the upper rotator being configured to be decoupled when the lower rotator and the upper rotator are rotated from the second relative rotation position to the first relative rotation position by an outside impact,
• the lower rotator including a first engagement portion fixedly thereon,
• the upper rotator including a second engagement portion fixedly thereon,
• the second engagement portion being configured, at least when the lower rotator and the upper rotator relatively rotate, to be into contact with the first engagement portion from a radial direction of the axis,
• at least one of the first engagement portion and the second engagement portion having elasticity,
• the at least one of the first and second engagement portions is deformed due to sliding contact with each other when relatively rotated from the first relative rotation position to the second relative rotation position,
• the first engagement portion and the second engagement portion being engaged at the second relative rotation position due to the elasticity of the at least one of the first and second engagement portions.
