Abstract: A spinner for a toy top enables a launching position of a toy top to be easily set and held in place even when a rack belt is vigorously pulled out. The spinner includes an elongated rack belt having a rack gear, and a spinner main body formed with an insertion hole through which the rack belt is inserted. The spinner main body includes a toy top mounting part rotatably provided on one surface thereof. Inside the spinner main body, a rotating mechanism that is actuated by pulling out the rack belt to impart a rotational force to the toy top mounting part is provided. The rack belt can be inserted into and pulled out from the insertion hole in a same direction an axis of rotation of the toy top mounting part.

Abstract: A low cost toy top having a simple structure and capable of changing its operating characteristics upon collision with an opponent toy top. The toy top which is spun on a playing board to play a match with an opponent toy top by being collided with the latter includes a main body including collisional portions adapted to come into contact with the opponent toy top, wherein at least some of the collisional portions are provided with a friction member for converting a rotational force of the opponent toy top into a rotational force of the toy top at the time of collision.

Abstract: A toy top capable of continuing to spin without its spinning being abruptly stopped by contacting a playing surface when the toy top wobbles with a reduction in rotational speed so as to spin longer than an opponent toy top. A toy top includes a shaft portion having a circular shape in cross-section and adapted to come into contact with a playing surface of the playing board for serving as a center of rotation when the toy top spins; a rotating plate having an insertion hole of an inner diameter greater than an outer diameter of the shaft portion, the rotating plate being attached to the shaft portion so as to freely rotate around the shaft portion while the shaft portion is inserted through the insertion hole; and an engagement for permitting the rotating plate to freely rotate and preventing the rotating plate from detaching from the shaft portion when the rotating plate is attached to the shaft portion.

Abstract: A safe spinner for a toy top which ensures that a rack gear formed on a rack belt will not directly contact a user's body during a pulling operation of the rack belt is provided. A spinner for a toy top includes a rotation imparting mechanism for imparting rotation to a toy top, having a rack gear and a pinion gear. The rack gear is formed on one surface of a belt body of an elongated plate-shape in such a manner that teeth of the rack gear protrude from the surface of the belt body and are arrayed in a longitudinal direction of the belt body. The belt body includes a pair of protection plates which is disposed on the surface thereof so that the plates face each other across the teeth of the rack gear, the pair of protection plates each being formed to have a height from the surface of the belt body equal to or greater than a height of the teeth of the rack gear.

Abstract: A spinner capable of imparting clockwise and counterclockwise rotation to a toy top by pulling a string. The spinner includes a spinner body, a first gear with string wound therearound, a second gear meshing with the first gear, and first and second toy top holders that rotate interlockingly with the second gear. The string has one end attached to the first gear and the other end can be pulled from the outside. The holders each include a portion for holding the toy top. The holding portions protrude from upper and lower surfaces of the spinner body, respectively. The holders are adapted to rotate the toy top clockwise and counterclockwise according to rotation of the second gear by pulling the string.

Abstract: A novel toy top capable of changing the operation mode in the course of spinning without replacing a component member constituting the toy top and having a simple structure and a low cost is provided. A toy top to be spun on a playing board with a playing surface curved in a concave mirror shape includes a shaft portion adapted to contact the playing surface, wherein the shaft portion has a circumferential surface provided with a friction portion that exhibits a coefficient of friction larger than the shaft portion at the time of contacting the playing surface, and the shaft portion has a tip protruding lower than the friction portion.

Abstract: A production method of an electroless plating material of the present invention is a method for the production of an electroless plating material that has a surface to be plated by electroless plating, and includes an ozone treatment step in which a material body that is made of a resin is brought into contact with a solution that contains ozone to form a modified layer in a surface of the material body, and a superficial layer removal step in which, after the ozone treatment step, the surface of the material body is irradiated with ultraviolet rays to remove a superficial layer of the modified layer.

Abstract: A toy top that can repeatedly jump on a curved playing surface to attack an opponent toy top from above. The jumping toy top includes a toy main body, a spinning shaft body having a spinning shaft, and a shaft body supporting portion disposed on the toy main body to support the spinning shaft body. A distal end of the spinning shaft has one side projecting downward more than another diametrically opposite side to configure a portion to contact a playing surface of a playing board. When the jumping toy top spins on a central axis of the toy main body, the contact portion revolves around the central axis of the toy main body in a circular orbit.

Abstract: A spinner for a toy top where a toy top can be spun by merely loading the toy top on the spinner and pulling a string. The spinner includes a spinner main body with a first gear having a string can be wound thereon, a second gear meshing with the first gear, and a toy top holder rotated according to rotation of the second gear. The first gear is linked with a member biasing the first gear in a winding direction of the string, one end of the string being attached to the first gear, and the other end thereof protruding from the spinner main body such that it can be pulled. The toy top holder includes a lower part protruded downwardly from a bottom face of the spinner main body and holding sections provided on a bottom face thereof for holding the toy top.

Abstract: A toy top which is played against an opponent toy top on a playing board including an upper layer member for attacking an opponent toy top, an intermediate layer member for determining a height of the toy top, and a lower layer member for determining a manner of moving of the toy top on a playing board, the members being stacked. The upper layer member is formed with an opening through which a screw of a screw-like coupling member is inserted, the intermediate layer member is formed with a screw hole to receive the screw of the coupling member, and the upper layer member and the intermediate member are coupled by the coupling member. The lower layer member is fitted to a lower part of the intermediate layer member.

Abstract: [Object] It is an object of the present invention to provide a marble having higher impact resistance than that of a marble of glass conventionally known, capable of being played by using a magnet and easily enhancing decorative properties. [Means for Settlement] A marble incorporating an iron core of a round ball is composed by covering the entire outer surface of an iron core with a jacket made of a synthetic resin.
