Top toy

1. A top toy for rotating in a first direction on a floor around a central axis extending in an axial direction, the top toy being arranged to collide with an opponent top toy, the top toy comprising:

first and second shaft side components, the first shaft side component extending in the axial direction; and

a trunk part being configured on the first shaft side component,

the trunk part including a trunk body, a moving member being rotatably configured with respect to the trunk body, and a locking mechanism,

the moving member being movable between first and second positions in the axial direction,

the locking mechanism being configured to lock releasably the moving member at the first position,

the first shaft side component being rotatably configured with respect to the trunk part between first and second rotation positions with the axial direction as a center,

the trunk part being rotatably configured with respect to the first shaft side component in a second direction being opposite to the first direction when an external force by colliding with the opponent top toy is applied to the trunk part,

the first shaft side component including a first projecting part,

when the first projecting part is in contact with the locking mechanism, the locking mechanism being configured to release the moving member from the first position,

the first shaft side component being interchangeable with the second shaft side component.

2. The top toy according to claim 1 , wherein

the moving member has a first ring surrounding the central axis, and

the first position is higher from the floor than the second position.

3. The top toy according to claim 2 , wherein

the first ring has rotation obstructed with respect to the trunk body at the first position, and is free to rotate with the central axis at the center at the second position.

4. The top toy according to claim 2 , wherein

the moving member has a second ring forming a portion of an outer periphery of the trunk part,

the second ring is configured on the first ring,

the second ring surrounds the central axis, and

the second ring is configured to be engaged with the first ring when the first ring is at the first position, wherein the second ring is obstructed to rotate with respect to the trunk body, and

the second ring is free to rotate with the central axis as the center when the first ring is in the second position.

5. The top toy according to claim 1 , wherein

the first shaft side component includes a first shaft part and a first flywheel,

the first projecting part is configured at a first position on the first flywheel,

the first shaft side component includes a second projecting part being configured at a second position on the first flywheel, and

the first position is different from the second position.

6. The top toy according to claim 5 , wherein

the second shaft side component includes a second shaft part and a second flywheel,

the second shaft side component includes third and fourth projecting parts,

positions of the first and second projecting parts are different from positions of the third and fourth projecting parts in a top view thereof.

7. The top toy according to claim 6 , wherein

the top toy has a first motion characteristic when the first shaft side component is equipped,

the top toy has a second motion characteristic when the second shaft side component is equipped,

the first and second motion characteristics are different.
