A spinning top toy including a body and a separate shaft portion. The body has a first hook and the shaft portion has a second hook. The body and the shaft portion are switchable between couplable and decouplable states depending on a relative rotational position. The first hook and the second hook are vertically aligned in the couplable state, and are vertically misaligned in the decouplable state. An urging unit brings an upper face of the first hook and a bottom face of the second hook into contact by an urging force of a spring in the couplable state. The body and the shaft portion enter the couplable state by turning and pushing. The body and the shaft portion engage each other by bringing the upper face of the first hook into contact with the bottom face of the second hook by the urging force of the spring.

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 toy assembly having a body symmetrically balanced around a first axis. The body has wheels upon which the body can roll. A flywheel is disposed within the body that rotates about the first axis in a plane that is perpendicular to said first axis. The flywheel preserves angular momentum. At least one gear is provided within the body that transfers rotational energy between the flywheel and at least one of the wheels. The toy assembly can roll as a vehicle or spin as a top depending on whether it is placed on a flat surface or balanced on a salient point.

A toy top includes a body and a bump for attack which is disposed on a circumference of the body. The bump moves up and down according to a force acting on the bump while the toy top spins.

A toy top includes a shaft part having, as a shaft center, an axis that coincides with a center of rotation. A lower end portion of the shaft part includes a shaft tip part and an annular member. The shaft tip part includes a contact member. The annular member is movably disposed around the shaft tip part in an extending direction of the axis. In a normal state in which the axis is perpendicular to a contact surface, the contact member protrudes from the annular member downward, and only the contact member contacts the contact surface. When the axis of the shaft part inclines with respect to the contact surface, the contact member and the annular member contact the contact surface.

A spinning top toy is configured to spin in a first direction, where the spinning top toy comprising includes a shaft part, a main body part, and a mounting member. The main body part is detachably configured to the shaft part. The main body is arranged to be detached from the shaft body when receiving a first amount of impact in a second direction opposite to the first direction. The mounting member is detachably configured on an outer periphery of the main body part. The mounting member is arranged to be detached from the main body when receiving an second amount of the impact in the second direction. The first amount being larger than the second amount.

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.
