  According to the toy disclosed in Patent Document 1, since the toy performs an action operation by the launch of the sphere and the sensing of the sensing member, the game performance is high. However, manual operation of launching the sphere may be difficult for infants around 1 year and 6 months old, and may not be able to play happily with this toy.

  Moreover, although the traveling toy disclosed in Patent Document 2 can enjoy the traveling of the toy itself, there are cases where the infant cannot enjoy it, for example, also as a play for launching a sphere.

  An object of the present invention is to provide a sphere launcher that can be easily handled even by infants and a traveling toy equipped with the sphere launcher.

The sphere launcher according to the present invention includes a sphere guide that guides the sphere from a sphere insertion port into which a sphere having a diameter larger than the interval between the tip of the pair of flip pieces and the tip of the flip piece is inserted to an inner position of the flip piece And a guided portion formed by combining a rod-shaped portion and a plurality of plate-like members extending in the longitudinal direction of the rod-shaped portion. A pushing member that pushes in, and the rod-like portion and the guided portion are guided by a guide portion .

  Further, a traveling toy according to the present invention has a case main body including the above-described spherical body launching device, a driven wheel, and a driving wheel, and the driving mechanism housed in the case main body is from a motor provided in the driving mechanism. A sphere launcher rotation transmission mechanism that transmits a rotational drive force to the sphere launcher, and a drive wheel rotation transmission mechanism that transmits a rotational drive force from the motor to the drive wheels are provided.

  According to the present invention, since the sphere inlet is formed slightly larger than the launching sphere, an object larger than the launching sphere cannot be used in the sphere launching device. Also, objects smaller than the sphere, such as marbles, are not fired because they do not hit the tip of the flip piece. The pushing member can be continuously operated by the driving mechanism. Therefore, it is possible to provide a sphere launching device that is easy to handle and fun for infants. Moreover, since the traveling toy according to the present invention having such a ball launching device can run the running toy while playing with the ball launching device, it is possible to provide a fun running toy that is easy for infants to handle.

  Embodiments of the present invention will be described with reference to the drawings. FIGS. 1A and 1B are perspective views showing the entire traveling toy 10 according to the present invention. The traveling toy 10 is shaped like a train. In the following description, the front of the train is the front, the rear of the train is the rear, and the right side when facing the front of the train is the right and the left side is the left.

  The traveling toy 10 includes a main body cover 20 and a carriage 30 as a case main body. The main body cover 20 is fixed on the carriage 30. As shown in FIG. 1A, the main body cover 20 is formed of a front portion 20a whose outer shape is a substantially cylindrical shape and a rear portion 20b which is a substantially box-shaped shape. At the rear of the upper surface of the rear portion 20b of the main body cover 20, a bowl-shaped sphere receiving portion 21 that guides the sphere to the sphere insertion port 52a is provided. A sensor 56 for detecting a passing sphere is disposed in the vicinity of the sphere insertion port 52a. The sensor 56 uses a limit switch in the present embodiment. A spherical launch port 54 is formed on the upper surface of the front portion 20 a of the main body cover 20. A cylindrical chimney cap 59 is provided on the outer periphery of the spherical launch port 54.

  Further, a push switch 23 having a shape imitating a character is provided in front of the spherical body receiving portion 21 on the upper surface of the rear portion 20b of the main body cover 20. On the left side between the spherical body receiving portion 21 and the push switch 23, a mode change push switch 24 having a rectangular top view is provided. As shown in the top view of FIG. 2, a star-shaped speaker 25 in a top view is provided on the right side between the spherical body receiving portion 21 and the push switch 23.

  Further, as shown in FIG. 1B, two slide switches are arranged up and down on the rear surface of the main body cover 20. The upper slide switch is a language selection switch 26, and the lower slide switch is a travel changeover switch 27. The language selection switch 26 can select, for example, either Japanese or English as the language of the sound emitted from the speaker 25. The traveling changeover switch 27 can switch between a traveling state in which the traveling toy 10 travels and plays, or a non-running state in which the traveling toy 10 does not travel.

  Two drive wheels 32 are provided behind the cart 30 below the traveling toy 10. Further, as mainly represented in FIG. 1B, a direction change wheel 36 that is engaged with the change groove 35 is provided on the lower surface front side of the carriage 30. The direction changing wheel 36 is a driven wheel. The conversion groove 35 includes a conversion front / rear groove 35a formed in the front / rear direction and a conversion right groove 35b extending rightward from the front end of the conversion front / rear groove 35a. The rotating shaft portion of the direction changing wheel 36 is engaged with a long hole formed on a side surface of the conversion groove 35 (the conversion front / rear groove 35a and the conversion right groove 35b). Accordingly, the direction change wheel 36 is supported by the change groove 35 so as to be rotatable and movable along the change groove 35.

  Further, a total of four dummy wheels 34 are provided in front of the carriage 30, two on each side. The dummy wheels 34 are rotatably provided, but are not grounded on the traveling surface. The driving wheel 32 and the direction changing wheel 36 are grounded on the traveling surface. Furthermore, a battery box cover 31 is disposed at the center of the lower surface of the carriage 30, thereby covering the battery box formed inside.

  In addition, an inclined protruding portion 38 having an inclined surface that is inclined so that a U-shaped surface in a plan view is projected rearward from the vicinity of the front end portion and gradually protrudes downward is formed in front of the center of the lower surface of the carriage 30. Yes. On the other hand, on the lower surface of the carriage 30 inside the left and right dummy wheels 34 on the rear side, arc-shaped projecting portions 39 are formed that project downward in an arc shape when viewed from the side. The height of the arcuate protrusion 39 from the lower surface of the carriage 30 is substantially the same as the height of the rear end portion of the inclined protrusion 38 and is lower than the drive wheels 32 and the direction change wheels 36. According to the inclined protruding portion 38 and the arc-shaped protruding portion 39, even if there is a slight step in the vertical direction on the traveling surface, the step is placed on the inclined surface of the inclined protruding portion 38, and the carriage 30 is inclined to the inclined protruding portion 38. Are supported by the inclined surface and the arcuate protrusion 39. Therefore, the traveling toy 10 can get over with a slight level difference. Further, the traveling toy 10 travels with three wheels, the direction changing wheel 36 and the left and right drive wheels 32. Therefore, when the traveling toy 10 is tilted forward left or right, the traveling toy 10 is supported by the arcuate protrusion 39, so that the traveling toy 10 does not tilt greatly.

  A user can play with the traveling toy 10 as follows. When the traveling changeover switch 27 is set to the traveling side, the user can easily insert the sphere into the sphere insertion port 52a by inserting the sphere into the sphere receiving portion 21 while the traveling toy 10 is traveling. The sphere inserted into the sphere input port 52a is launched directly from the sphere launch port 54. The traveling of the traveling toy 10 is set to repeat forward and backward. Then, as the traveling toy 10 moves forward and backward, the direction change wheel 36 on the lower surface of the carriage 30 is switched so as to be positioned in the front / rear groove 35a and the right turn groove 35b, so that the traveling toy 10 repeats a left turn and a right turn at random. Will run.

  In this way, even an infant starting to walk can play by putting the sphere into the sphere insertion port 52a in the manner of ball insertion while chasing the traveling toy 10 that the infant travels forward, backward, left and right and unexpectedly travels. it can. And since the thrown-in sphere is launched right above the sphere launch port 54 having the appearance of the chimney cap 59, it can be recalled that smoke is discharged from the chimney, and the infant can further enjoy it.

  Further, when the travel switch 27 is set to the non-traveling side, the traveling toy 10 does not travel. Even in this case, when a sphere is inserted into the sphere insertion port 52a, the sphere is launched directly from the sphere launch port 54. Therefore, even an infant who cannot walk yet can play with the traveling toy 10.

  In addition to the above-described ball insertion play by the traveling toy 10, the traveling toy 10 performs various kinds of play such as play counting the number of inserted spheres by detecting the sphere with the push switch 23 or the sensor 56 simulating a character. Can be set. The selection of these ways of playing can be appropriately switched by the mode switching push switch 24.

  Next, the internal structure of the traveling toy 10 will be described. Here, FIG. 3 is a perspective view of the traveling toy 10 as viewed from the rear with the main body cover 20 omitted. Further, FIG. 4 omits the main body cover 20, the carriage 30, the push switch 23, and the like, and shows the spherical body receiving portion 21, the spherical body guide 52, the surrounding member 55, the mounting ring 57, and the chimney cap 59 as vertical sections. It is the perspective view seen from the front.

  As shown in FIG. 3, in the traveling toy 10, a drive mechanism 80 that is housed in the case body is provided on the carriage 30. The drive mechanism 80 drives the drive wheel 32 and the push member 51 of the sphere launcher 50 described later. The drive mechanism 80 includes a gear box 81 and stores a large number of gears that transmit a driving torque. As mainly shown in FIG. 4, a motor 82 is provided slightly above the left side surface of the gear box 81. A rotating cam 88 is provided on the left side surface near the front end of the gear box 81. The rotating cam 88 is formed with a cylindrical cam follower 88b from the left side surface of the disc-shaped substrate 88a toward the left side. The rotational force of the motor 82 is transmitted by the drive mechanism 80, and the rotary cam 88 is rotated at a constant speed in the direction of arrow A, which is one of the clockwise directions when viewed from the left side.

  A swinging member 89 is provided on the front side of the rotating cam 88. The swing member 89 is formed in a long flat bar shape. The swing member 89 has a fulcrum 89a at the center in the longitudinal direction. The swing member 89 is freely swingable around the fulcrum 89a so that the front and rear ends of the swing member 89 can be moved up and down. On the rear side, which is one side of the swing member 89, a cam guide portion 89b formed in a long hole shape along the longitudinal direction is formed. The cam follower 88b of the rotating cam 88 is engaged with the cam guide portion 89b.

  In addition, a push member 51 is provided in front of the swing member 89. As shown in FIGS. 4 and 2, the pressing member 51 has a rod-like rod-shaped portion 51a whose outer shape in a cross section is circular and long in the vertical direction, and extends downward from the upper end to the front side of the rod-shaped portion 51a. A plurality of plate-like members are combined to form a guided portion 51b having a cross-shaped outer shape in a cross shape. The guided portion 51b may have a T-shaped outer cross section. However, if a cross shape is used as in the present embodiment, the gap between the inner surface of the enclosing member 55 described later and the guided portion 51b can be reduced (see FIG. 2). Insertion of foreign matter can be reduced.

  Furthermore, the front end surface of the rod-like portion 51a of the pressing member 51 is an inclined portion 51a1 that is inclined so as to descend to the side opposite to the sphere insertion port 52a (that is, forward). Thereby, the sphere positioned on the front end surface of the pressing member 51 is pressed against the inner side surface of a surrounding member 55 described later in front of the pressing member 51. Therefore, the sphere pushed upward by the pushing member 51 is pushed straight up along the inner surface of the surrounding member 55. Further, as shown in FIG. 4, a rectangular hole 51c having a front view rectangular shape is opened in the front-rear direction in the vicinity of the lower end portion of the rod-like portion 51a. The lower end of the guided portion 51b reaches the upper end of the square hole 51c. The front end portion which is the other side of the above-described swinging member 89 is inserted into the square hole 51c. In this way, a connecting portion between the pressing member 51 and the swing member 89 is formed.

  The push member 51 is moved up and down as follows. First, when the rotary cam 88 rotates in the A direction from the state of FIG. 4, the rear end of the swing member 89 is lowered and the front end of the swing member 89 is raised. Accordingly, the push member 51 rises. When the cam follower 88b of the rotating cam 88 passes the lower limit position of the rotating cam 88, the rear end of the swing member 89 gradually rises. Then, the front end of the swing member 89 is lowered. Accordingly, the push member 51 is lowered.

  Note that the sphere is fired from the flip piece 53, which will be described later, against the resilience of the flip piece 53 while the sphere passes the tip of the flip piece 53. At this time, in the rotating cam 88, the cam follower 88b rotates from the position (upper limit position) in FIG. 4 toward the lower limit position (that is, the push member 51 gradually rises). Therefore, when the rotating cam 88 is rotated in the A direction, the distance between the cam follower 88b and the fulcrum 89a can be increased. Therefore, according to the so-called lever principle, the rotating cam 88 is rotated in the direction opposite to the A direction. In comparison, the motor 82 can be made smaller, and the manufacturing costs can be reduced.

  A pair of repelling pieces 53 formed by injection molding of a resin material is provided above the connecting portion (that is, the portion of the square hole 51c) between the swing member 89 and the pressing member 51. That is, the pair of playing pieces 53 includes a left playing piece 53-1 and a right playing piece 53-2. The flip piece 53 includes a substantially plate-like base end portion 53a whose plane is directed in the left-right direction. A curved portion 53b that extends upward from the base end portion 53a and curves outward is formed above the base end portion 53a. A projecting portion 53 c that projects outward is formed from the tip of the flip piece 53.

  Here, as shown in FIG. 5, the predetermined interval S at which the distal ends of the curved portions 53b of the pair of flip pieces 53 are set to be smaller than the diameter D of the sphere P1. The sphere P1 is formed of a resin material with a hollow inside, but may be a sphere having another known configuration. Further, a chamfered portion 53b1 is formed on the rear side of the distal end portion of the curved portion 53b of the pair of flip pieces 53 so that the sphere can be easily introduced.

  A substantially cylindrical enclosing member 55 is formed on the outer periphery from the vicinity of the lower end of the pressing member 51 to the vicinity of the upper end of the flip piece 53. The repelling piece 53 has a base end portion 53a fixed to an attachment portion on the inner peripheral surface of the surrounding member 55 (see FIGS. 5 to 7). A partition plate 53d is formed in the upper part of the base end portion 53a of the flip piece 53 in parallel in the horizontal direction.

  As shown in FIG. 2, a hole 53 e having the same shape as the top view of the pressing member 51 is formed in the partition plate 53 d to serve as a guide portion that guides the vertical movement of the pressing member 51. The hole 53e is a hole in which both are continuous by a circular bar-shaped guide part 53e1 that guides the bar-shaped part 51a and a guide part 53e2 that guides the guided part 51b that is cross-shaped when viewed from the top. Further, although not shown in detail, a partition plate 55c is formed on the lower inner peripheral surface of the surrounding member 55 in FIG. The partition plate 55c is also formed with a hole having the same shape as the hole 53e, and serves as a guide portion that guides the vertical movement of the pressing member 51. Since the pushing member 51 is guided by the guide portions in the guided portion 51b and the partition plate 55c, the pushing member 51 is straightly guided and operated even when a force is received during the launching operation of the sphere.

  Further, the inner peripheral surface of the surrounding member 55 corresponding to the pair of playing pieces 53 (the left playing piece 53-1, the right playing piece 53-2) protrudes outward and the escape portion 55a when the playing piece 53 is opened. Are formed on the left and right respectively (see also FIGS. 5 to 7). Further, on the inner peripheral surface corresponding to the overhang portion 53c of the flip piece 53 in the vicinity of the upper end portion of the surrounding member 55, the overhang portion 53c is released when the flip piece 53 is opened (in other words, the overhang portion 53c). A hole 55b is formed (also, see FIGS. 5 to 7).

  A chimney cap 59 having an appearance simulating a chimney of a train is provided at the upper end of the surrounding member 55 via an annular mounting ring 57. The chimney cap 59 is detachably attached to the mounting ring 57. As a result, even if the sphere is positioned on the top of the flip piece 53 and the infant cannot take out the sphere, the parent can easily remove the sphere on the top of the flip piece 53 by removing the chimney cap 59. It can be taken out.

  On the other hand, returning to FIG. 4, the guide body 52b of the sphere guide 52 including the sphere insertion port 52a is formed in a cylindrical shape and is inclined from the rear to the front so that the front side is lowered. The diameter of the sphere insertion port 52a is formed to be slightly larger than the diameter of the sphere (diameter D of the sphere P1 in FIG. 5) to the extent that the sphere can be inserted. Therefore, a sphere larger than the sphere for the traveling toy 10 cannot be thrown. Although an object smaller than the sphere can be inserted, as described above, it is not accidentally fired by the sphere launcher 50 if it is smaller than the interval S (see FIG. 5) of the tip of the flip piece 53. . If the object is larger than the interval S and smaller than the diameter D of the sphere P1, the tip of the repelling piece 53 is not sufficiently hooked, so that it is not vigorously fired by the sphere launcher 50. Further, a guide plate 52c is formed on the lower side of the front end of the guide main body 52b to guide the spherical body to be disposed at the inner position of the flip piece 53 (see also FIG. 2).

  The operation of the sphere launcher 50 is as follows. The sphere P1 inserted into the sphere input port 52a shown in FIG. 4 passes through the guide main body 52b, rolls on the guide plate 52c, and is arranged inside the curved portion 53b of the flip piece 53, resulting in the state shown in FIG. . Here, the pressing member 51 continuously advances and retreats at a constant speed from the base end portion 53a of the flip piece 53 to the tip end. Therefore, as shown in FIG. 5, when the sphere P <b> 1 is disposed inside the flip piece 53 and positioned on the tip of the push member 51, the sphere P <b> 1 is pushed toward the tip of the flip piece 53 by the push member 51. Then, the flip piece 53 opens left and right by the sphere P1.

  When the sphere P1 is further pushed in by the pushing member 51 and the upper half of the sphere P1 passes between the tips of the flip pieces 53 as shown in FIG. 6, the sphere P1 is caused by the elastic force of the pair of flip pieces 53 closing. Are fired upwards. With the launch of the sphere P1, the flip piece 53 is closed to the state shown in FIG. When the next sphere P2 has been inserted into the sphere insertion port 52a, the pusher member 51 is lowered to the bottom, so that the next sphere P2 is positioned inside the curved portion 53b of the flip piece 53.

  Here, the height T of the projecting portion 53c shown in FIG. 7 is the sphere P1 when positioned at the tip of the projecting portion 53c and the next sphere P2 when positioned inside the curved portion 53b of the flip piece 53. The height is set apart. Thereby, even when the sphere P1 is positioned at the tip of the overhanging portion 53c, the sphere P1 and the next sphere P2 do not interfere with each other, and the next sphere P2 is introduced inside the curved portion 53b of the flip piece 53. The sphere can be continuously fired by the sphere launch device 50.

  In this way, the flip piece 53 is opened and closed. At this time, the protrusion 53c at the tip of the flip piece 53 reduces the intrusion of a finger or a foreign object from the chimney cap 59 between the outer surface of the curved portion 53b and the inner peripheral surface of the surrounding member 55. .

  Next, the drive mechanism 80 for driving the drive wheel 32 and the push member 51 of the sphere launcher 50 will be described in detail. FIG. 8 is a rear perspective view showing the inside of the gear box 81 with the right side of the gear box 81 omitted.

  A pinion gear 83 is provided on the drive shaft of the motor 82 of the drive mechanism 80. The drive mechanism 80 includes a drive wheel rotation transmission mechanism 100 and a sphere launcher rotation transmission mechanism 120.

  First, the drive wheel rotation transmission mechanism 100 will be described. In the driving wheel rotation transmission mechanism 100 that drives the driving wheel 32, a driving wheel side first two-stage gear 101 is provided on the lower rear side of the pinion gear 83. The drive wheel side first two-stage gear 101 is provided to be rotatable with respect to an axis fixed to the gear box 81. The driving wheel side first two-stage gear 101 includes a large gear 101a having a large diameter and a small gear 101b having a small diameter that protrudes to the right of the large gear 101a and is coaxially disposed. The large gear 101 a of the drive wheel side first second gear 101 is engaged with the pinion gear 83.

  A driving wheel side second two-stage gear 102 is provided above the driving wheel side first two-stage gear 101. The drive wheel side second two-stage gear 102 is provided so as to be rotatable with respect to a shaft fixed to the gear box 81. The drive wheel side second two-stage gear 102 includes a large gear 102a and a small gear 102b protruding from the right side surface of the large gear 102a. The large gear 102a of the driving wheel side second two-stage gear 102 meshes with the small gear 101b of the driving wheel side first two-stage gear 101.

  Below the driving wheel side second two-stage gear 102, a driving wheel side third two-stage gear 103 is provided. The drive wheel side third two-stage gear 103 rotates coaxially with the drive wheel side first two-stage gear 101, that is, rotates on an axis fixed to the gear box 81 and provided with the drive wheel side first two-stage gear 101. It is provided freely. The drive wheel side third two-stage gear 103 includes a large gear 103a and a small gear 103b protruding from the right side surface of the large gear 103a. The large gear 103a of the driving wheel side third two-stage gear 103 meshes with the small gear 102b of the driving wheel side second two-stage gear 102.

  Below the drive wheel side third second gear 103, a drive wheel side fourth second gear 104 is provided. The drive wheel side fourth two-stage gear 104 is provided so as to be rotatable with respect to a shaft fixed to the gear box 81. The drive wheel side fourth two-stage gear 104 includes a large gear 104a and a small gear 104b protruding from the right side surface of the large gear 104a. An annular chamfer 104b1 is formed at the outer peripheral tip of the small gear 104b (see also FIGS. 9A and 9B). The large gear 104 a of the drive wheel side fourth second gear 104 meshes with the small gear 103 b of the drive wheel side third second gear 103.

  A slide gear 105 is disposed behind the drive wheel side fourth second gear 104. The slide gear 105 is provided so as to be rotatable with respect to an axis fixed to the gear box 81 and to be movable in the left-right direction. Further, as shown in FIG. 9, the shaft on which the slide gear 105 is provided between the boss 105 a on the left side surface of the slide gear 105 and the inner surface of the left side plate 81 a of the gear box 81 is wound around the shaft. A coil spring 106 is provided as an elastic member. The coil spring 106 prevents the slide gear 105 from moving unexpectedly to the traveling side (that is, the left side) when the non-traveling state is selected.

  The slide gear 105 is supported such that the left and right side surfaces are sandwiched between a pair of sandwiching support portions 27a formed below the travel changeover switch 27 and extending forward. The travel changeover switch 27 is slidable in the left-right direction.

  A drive gear 107 is provided below the slide gear 105. The drive gear 107 is fixed to the drive shaft 108. The drive shaft 108 is fixed to both ends of the drive wheel 32 and is rotatably provided with respect to the carriage 30 (see FIG. 3).

  Transmission of the rotational driving force by the drive wheel rotation transmission mechanism 100 is performed as follows. First, when the motor 82 is activated and the pinion gear 83 rotates, the driving wheel side first two-stage gear 101 rotates, and the driving wheel side second two-stage gear 102, the driving wheel side third two-stage gear 103, and the driving wheel sequentially. The side fourth second gear 104 rotates. Here, when the slide switch of the travel changeover switch 27 is slid to the left and the travel side is selected, as shown in FIG. 9A, the slide gear 105 of the drive wheel rotation transmission mechanism 100 is the first on the drive wheel side. 4 meshes with the small gear 104b of the two-stage gear 104. Then, the rotational force of the drive wheel side fourth two-stage gear 104 is transmitted to the slide gear 105 and is transmitted to the drive gear 107, and the drive wheel 32 rotates.

  On the other hand, when the travel changeover switch 27 is slid to the right side and the non-traveling side is selected, the slide gear 105 is a small gear of the drive wheel side fourth two-stage gear 104 as shown in FIG. It moves to a position where it does not mesh with 104b. At this time, since the small gear 104b of the drive wheel side fourth second gear 104 and the slide gear 105 are not engaged with each other, the rotational force of the drive wheel side fourth second gear 104 is driven by the drive gear 107. Is not communicated to. Therefore, the driving wheel 32 is not driven, and the transmission of the driving force to the driving wheel 32 by the motor 82 is interrupted.

  Thus, the drive wheel rotation transmission mechanism 100 includes a transmission switching device formed by the slide gear 105, the coil spring 106, and the travel switch 27. Accordingly, the traveling switch 27 can switch between the traveling state and the non-traveling state of the traveling toy 10.

The launch side third two-stage gear 125 includes a large gear 125 a and a small gear 125 b protruding from the right side surface of the large gear 125 a, and is rotatably provided on a shaft fixed to the gear box 81. The large gear 125 a of the firing side second two-stage gear 125 meshes with the small gear 124 b of the firing side second second gear 124.

  Below the firing-side third two-stage gear 125, a firing-side fourth two-stage gear 126 is provided. The launch side fourth stage gear 126 includes a large gear 126a and a small gear 126b protruding from the right side surface of the large gear 126a, and is rotatably provided on a shaft fixed to the gear box 81. The large gear 126 a of the firing side second two-stage gear 126 meshes with the small gear 125 b of the firing side third second stage gear 125.

  A launch side fifth gear 127 is provided in front of the launch side fourth second gear 126. The launch side fifth gear 127 is rotatably provided on a shaft fixed to the gear box 81. The firing side fifth gear 127 meshes with the small gear 126b of the firing side fourth two-stage gear 126.

  A launch side sixth gear 128 is provided in front of the launch side fifth gear 127. The launch side sixth gear 128 is rotatably provided on a shaft fixed to the gear box 81. The launch side sixth gear 128 is connected to the rotary cam 88 through a constant velocity joint 129.

  In this way, the sphere launcher rotation transmission mechanism 120 is composed of a large number of gears. Here, the motor 82 repeats normal rotation and reverse rotation so that the traveling toy 10 can enjoy traveling, and moves the traveling toy 10 forward and backward. However, the rotating cam 88 is rotated in a fixed direction (A direction in FIG. 4) as described above. Accordingly, transmission of the rotational driving force of the sphere launcher rotation transmission mechanism 120 is performed as follows.

  When the motor 82 rotates forward, the pinion gear 83 rotates in the B1 direction as shown in FIG. Then, the rotation direction switching gear 121 is rotated in the C1 direction (reverse rotation direction) and receives the rotational force from the pinion gear 83 and is positioned at the lower end position that is one end of the gear guide groove 84a1. The rotation direction switching gear 121 meshes with the large gear 123a of the firing side first second stage gear 123 to rotate the firing side first second stage gear 123 in the D direction (forward rotation direction). At this time, the switching small gear 122 idles in the E direction (reverse direction).

  When the firing side first second gear 123 is rotated in the D direction (forward rotation direction), the firing side second second gear 124, the firing side third second gear 125, the firing side fourth second gear 126, sequentially, The firing side fifth gear 127 and the firing side sixth gear 128 rotate, and the rotating cam 88 rotates in the A direction.

  On the other hand, when the motor 82 rotates in reverse, the pinion gear 83 rotates in the B2 direction (reverse rotation direction) as shown in FIG. Then, the rotation direction switching gear 121 is rotated in the C2 direction (forward rotation direction), receives the rotational force from the pinion gear 83, moves along the gear guide groove 84a1, and is an upper end that is the other end of the gear guide groove 84a1. Located in position. Then, the rotation direction switching gear 121 meshes with the switching small gear 122. The small switching gear 122 rotates in the E direction (reverse direction). Thereby, the launch side first two-stage gear 123 rotates in the D direction (forward rotation direction). As a result, the subsequent rotation is the same as described above, and the rotating cam 88 rotates in the A direction.

  As described above, the sphere launcher rotation transmission mechanism 120 includes the rotation direction switching gear 121, the gear guide groove 84a1, and the rotation guide 88 so that the rotation cam 88 is rotated in one direction (A direction) regardless of the rotation direction of the motor 82. A rotation direction switching device including a switching small gear 122 is provided. Therefore, even if the drive source (motor 82) of the drive wheel rotation transmission mechanism 100 and the sphere launcher rotation transmission mechanism 120 is used in common and the drive wheel 32 is configured to repeat normal rotation or reverse rotation, the rotation cam 88 is set in a fixed direction. Can continue to rotate.

  As mentioned above, although embodiment of this invention was described, this invention can be implemented by adding various changes, without being limited by this embodiment. For example, the advance / retreat operation of the push member 51 is operated by the swing member 89 and the rotary cam 88, but other known cam structures may be used. Further, the sphere launch device 50 of the traveling toy 10 is configured to launch a sphere upward, but may be launched in a different direction such as right side or obliquely upward.
