A spinning top toy includes a shaft part, and a body configured on the shaft part at a first longitudinal end thereof. The shaft part includes a shaft main body part in which an axis line corresponding to a rotation center is defined as a shaft center, and a shaft holding part holding the shaft main body part. The shaft main body includes a ground contact member configured at a second longitudinal end of the shaft part opposite to the first longitudinal end. The ground contact member has an annular-shaped ground contact part being arranged to be in contact with a contact surface and being elastically deformable. The ground contact member is rotatable with respect to the shaft holding part.

A spinning top toy used for battle games in which the spinning top toy collides with an opponent spinning top toy includes a shaft part, a body, and first and second gripping members. The body is configured on the shaft part. The first and second gripping members are configured on at least a part of an outer periphery of the body. One of the first and second gripping members is urged to the other of the first and second gripping members to have a first distance therebetween. The first and second gripping members are separated to have a second distance therebetween when the shaft part is rotated. The first distance is smaller than the second distance.

An angular momentum spinner includes two or more rotating arms loaded with an adjustable sliding block for each arm and laid symmetrically about a rotating center. Each sliding block is controlled to move along the corresponding rotating arm. Such a spinner can display the conservation of angular momentum vividly and intuitively, and can also serve as an amusing toy for children. The spinner can be used as teaching equipment for various students to demonstrate the theorem of angular momentum conveniently, intuitively and amusingly.

A top launching device for launching a top includes a device body and an operating belt. The device body includes first and second input rotors to rotate, an output rotor configured to hold the top in a state with a central axis of the output rotor aligned with a central axis of the top and configured to rotate and impart the rotational force to the top, and a coupling rotor configured to transmit the rotational force from the input rotor to the output rotor. The operating belt is configured to be inserted in the device body, and to be engaged with either the first or the second input rotor. The output rotor is configured to rotate the top, impart the rotational force to the top, and release the top. The operating belt is configured to be selectively engaged with one of the first and second input rotors.

A top toy includes a first shaft side component and a trunk part. The trunk part includes a trunk body, a moving body being rotatably configured with respect to the trunk body, and a locking mechanism. The locking mechanism is configured to lock releasably the moving member at a first position. The first shaft side component is rotatably configured with respect to the trunk part between first and second rotation positions. The trunk part is rotatably configured with respect to the first shaft side component when an external force is applied to the trunk part. The first shaft side component includes is a first projecting part. When the first projecting part is in contact with the locking mechanism, the locking mechanism is configured to release the moving member from the first position. The first and second shaft side components are interchangeable.

A transformable toy kit for use on a support surface is provided. The transformable toy kit includes a transformable toy which has a movable housing element that moves between retracted and expanded positions when a catch and a latch of the transformable toy are secured and released by an actuator of the transformable toy, respectively. The transformable toy further includes a shaft assembly including a shaft rotatably mounted within the housing, and a flywheel mounted to the shaft, which includes a gear. The kit includes a ripcord member that is insertable into an access aperture in the housing to engage with the gear. The ripcord member is pullable once inserted into the access aperture so as to drive rotation of the flywheel, thereby driving spinning of the transformable toy.

A top toy is used in a game table including a guide member having a guide surface on which first teeth are formed at an equal interval. The top toy includes a shaft part, a body being configured on the shaft, and a trunk part being configured on the shaft. The shaft includes second teeth that are engageable with the first teeth on an outer periphery thereof.
