  In the conventional track device, the insertion piece of one track device is inserted and connected to the insertion port of the other track device, but the metal rails do not come into contact with each other reliably. A holding portion for electrically connecting the end portions of each other must be formed separately, and the structure is complicated. Therefore, for example, it is difficult to downsize the track device so that the distance between the rails is about 3 mm. Therefore, there is a problem in that an extremely small vehicle toy cannot be formed. Further, the conventional method for manufacturing a track device has a problem that the structure is complicated and a small track device cannot be manufactured.

(C) A third step of attaching a magnet to an attachment portion formed at one end of the orbital belt.
(D) A fourth step of attaching the bottom plate to the bottom of the orbital belt.

In the track device according to the present invention, when the insertion protrusion of the metal rail of the other track band is inserted into the insertion recess of the track band, the insertion protrusion of the other metal rail is adsorbed by the magnet, The rails can be connected to other metal rails via magnets, and thus other track zones can be coupled. Moreover, the track apparatus according to the present invention can easily release the connection between the metal rails and the connection between the track bands by separating the track bands with a force greater than the magnetic force of the magnet. As described above, the track device according to the present invention is functional and can simplify the structure because it can simultaneously connect the metal rails with the magnets and connect and disconnect the connection of the track bands. There is an effect. Therefore, the track device according to the present invention has an effect that it can be reduced in size and weight. Furthermore, since the track device according to the present invention can be reduced in size and weight, there is an effect that the connection and connection functions can be sufficiently performed by the magnetic force of the magnet.

In contact with the magnet 250. The track devices 201 are connected to each other by the attractive force of the magnet 250. In this way, the track device 201 can be connected linearly or annularly. Since the magnet 250 has conductivity, a current can flow through the entire metal rail 261 of the track device 201 connected linearly or annularly.

  The drive wheel device 1, 1 and the driven wheel device 31, 31 of the powered vehicle toy 101 can be mounted on the metal rails 261, 261 of the track device 201. As shown in FIG. 16, the second wheel main bodies 21 and 21 and the fourth wheel main bodies 51 and 51 formed by magnets are alternately grounded to the metal rails 261 and 261. The positive electrode of the power supply is connected to one of the metal rails 261 (referred to as 261A), and the negative electrode of the power supply is connected to the other of the metal rails 261 (referred to as 261B).

  As shown in FIG. 3, from the one of the fourth wheel main bodies 51 (referred to as 51A) that is grounded to the metal rail 261A, the current flows from the conductive ring 60, the first conductive contact 141, the spring 155, Spring holding piece 156, positive terminal of drive motor 116, negative terminal of drive motor 116, other spring holding piece 156, spring 155, second conductive contact 145, conductive ring 60, and other of fourth wheel main body 51 ( 51B) to the metal rail 261B. The drive motor 116 is rotated by this current, and the rotation is transmitted to the gears 8 and 8 through the gear group 120, and the drive wheel devices 1 and 1 rotate on the metal rails 261 and 261. In this way, the powered vehicle toy 101 can travel on the track device 201.

  In the power vehicle toy 101, while the vehicle is running on a curve, the inner wheel rotates slowly and the outer wheel tries to rotate faster, but the wheel on the side that is not attracted to the magnet slides on the rail. Compared to conventional vehicle toys that rotate while being attracted, there is less resistance to magnetic force, and the load on the drive motor 116 is less.

  The passenger vehicle toy 161 is connected to the powered vehicle toy 101, and the driven wheel devices 31, 31, 65, 65 of the passenger vehicle toy 161 can be placed on the metal rails 261, 261 of the track device 201. The positive electrode of the power supply is connected to one of the metal rails 261 (referred to as 261A), and the negative electrode of the power supply is connected to the other of the metal rails 261 (referred to as 261B).

  The current flows from one of the fourth wheel bodies 51 (referred to as 51C) that is grounded to the metal rail 261A to the conductive ring 60, the first conductive contact 141, the spring 155, one spring pressing piece 156, the light emitting element, and the like. The other spring pressing piece 156, the spring 155, the second conductive contact 145, the conductive ring 60, and the other of the fourth wheel body 51 (referred to as 51D) flow to the metal rail 261B. This electric current activates the electrical components in the vehicle toy body 162.

  The power vehicle toy 101 and the passenger vehicle toys 161 and 171 travel on metal rails 261 and 261 that are extremely small and have a distance of about 3 mm. The power vehicle toy 101 and the passenger car vehicle toys 161 and 171 are extremely lightweight, but the second wheel body 21 of the driving wheel device 1 and the fourth wheel body 51 of the driven wheel device 31 that are in contact with the metal rail 261 are included. Since the second wheel body 21 and the fourth wheel body 51 are formed by magnets, the second wheel body 21 and the fourth wheel body 51 are attracted to the metal rail 261 by magnetic force, and the rotation of the driving wheel device 1 and the driven wheel device 31 slides on the metal rail 261. Even if there is an ascending slope, it travels reliably. Further, since the second wheel main body 21 of the driving wheel device 1 and the fourth wheel main body 51 of the driven wheel device 31 are adsorbed to the metal rail 261 by magnetic force, there is a possibility that the second wheel main body 21 falls off the metal rail 261 and falls. Few.

When the track device 201 inserts the insertion protrusion 281 of the metal rail 261 of the other track band 202 into the insertion recess 272 of the track band 202, the insertion protrusion 281 of the other metal rail 261 becomes the magnet 250. The metal rail 261 can be connected to the other metal rail 261 via the magnet 250, and the other track band 202 can be coupled in this manner. Moreover, the track apparatus 201 can easily release the connection between the metal rails 261 and the connection between the track bands 202 by separating the track bands 202 with a force greater than the magnetic force of the magnet 250.
As described above, the track device 201 is functional and can simplify the structure because it can simultaneously connect the metal rail 261 with the magnet 250 and connect the track band 202 and release the connection and connection. it can. Accordingly, the track device 201 can be reduced in size and weight so that the distance between the metal rails 261 and 261 is about 3 mm. Furthermore, since the track device 201 can be reduced in size and weight, the function of the connection and connection can be sufficiently achieved by the magnetic force of the magnet 250. The track device 201 is manufactured by inserting a pair of metal rails 261 and 261 into a pair of grooves 215 and 216 of the track band 202 and bending the locking claws 275, 278, 279 and 282 of the metal rails 261 and 261. The metal rails 261 and 261 can be fixed to the raceway band 202 only by doing so, and the manufacture is extremely easy.
