Further, a lower opening 148 is formed in a front portion of the contact plate main body housing portion 145, in a bottom surface of the contact plate main body housing portion 145, so as to communicate with a rear side of the through hole 143 and with a lower side of the bottom plate 141.

The switch movable body 210 has side portions 212 standing upright from the left and right rotation ends of the rod-shaped body 211, and has protruding portions 214 protruding laterally outward from the upper end portions 213 of the side portions 212, and a recessed portion 217 is formed in the space above the body 211 sandwiching the left and right side portions 212.

Further, the switch movable member 210 is inserted into the through hole 143, as shown in fig. 3, the main body 211 protrudes downward from the bottom plate 141, the left and right side surfaces and the front and rear side surfaces of the left and right side portions 212 contact the peripheral surface of the through hole 143 to be movable up and down, the protruding portion 214 contacts the upper surface of the bottom plate 141 to prevent the falling off from the bottom plate 141, the recessed portion 217 accommodates the vicinity of the contact portion 245 of the rocking contact plate 240 and the vicinity of the switch contact portion 237 of the 2 nd wire guide 230, and the vicinity of the contact portion 245 of the rocking contact plate 240 is supported on the upper surface of the main body 211.

As shown in fig. 5, the rocking contact plate 240 has: a rectangular flat plate-shaped main body 241 having a longitudinal axis in the front-rear direction; a flat plate-shaped vertical portion 243 having the same width as the main body portion 241 and standing upright from the rear end of the main body portion 241; and a tongue-shaped electric wire connection portion 249 having bilaterally symmetric flat bar-shaped arm portions extending leftward and rightward from the substantial center of the main body portion 241 and having a width smaller than that of the main body portion 241, the substantially center of the main body portion 241 being formed by cutting in a U-shape.

The swinging contact plate 240 formed into a cross shape by the body portion 241 and the arm portion is accommodated in the contact plate body accommodating portion 145 and the contact plate arm accommodating portion 146 of the base plate 141, and is accommodated in the contact plate arm accommodating portion 146 of the contact plate body accommodating portion 145 with a slight gap in the periphery.

As shown in fig. 3, the rocking contact plate 240 is configured such that the auxiliary support projections 147 formed in the contact plate arm receiving portions 146 support the end portions of the support arm portions 247 from below, thereby ensuring a state of being slightly lifted from the bottom surface of the contact plate main body receiving portion 145 and the like, and the tip of the contact plate pressing portion 135 protruding downward in front of the lower end of the side plate 131 is disposed at the position closest to the upper surface of the support arm portion 247 at the position facing the auxiliary support projections 147.

The upper end 244 of the vertical portion 243 is provided in the vicinity of the lower portion of the magnetic pole surface peripheral edge portion closest to the lower end of the rear magnetic pole surface of the permanent magnet 151, and is set so as to attract the vertical portion 243 of the rocking contact plate 240 by the permanent magnet 151.

Therefore, as shown in fig. 3, in the vicinity of both ends of the support arm portions 247 on the left and right sides, the upper surfaces of the support arm portions 247 abut on the contact plate pressing portions 135 of the side plates 131, the vertical portions 243 and the rear ends of the main body portion 241 are brought close to the permanent magnets 151, the front end of the main body portion 241 and the contact portion 245 are disposed downward, and the switch movable body 210 is pressed down to generate a gap between the contact portion 245 and the switch contact portion 237.

Then, after the switch movable body 210 is pushed up from below by an external force, the contact portion 245 is brought into contact with the switch contact portion 237 so as to swing about the contact plate pressing portion 135 in order to slightly increase the distance between the upper end 244 of the vertical portion 243 and the magnetic pole surface end of the permanent magnet 151, thereby allowing conduction between the 2 nd lead plate 230 and the swing contact plate 240.

The external force of the contact 245 and the switch contact 237 is set to be larger than the self weight of the movable switch member 210 and smaller than a fraction or even about a tenth of the self weight of the entire walking toy 100, so as to adjust the distance between the upper end 244 of the vertical portion 243 and the end of the magnetic pole surface of the permanent magnet 151, and the attraction force of the permanent magnet 151 to the vertical portion 243 is set by pushing up the tip of the rocking contact 240 with a force smaller than a fraction of the self weight of the entire walking toy 100 by the movable switch member 210.

Therefore, when the front leg portion 149 and the rear leg portion 168 of the walking toy 100 are positioned upward and the ears 112, the back, and the like are in contact with the flat surface, the vertical portion 243 is attracted by the permanent magnet 151, and the contact portion 245 is separated from the switch contact portion 237, so that the switch 200 can be turned off.

When the walking toy 100 is lifted to a substantially horizontal position with the front leg portion 149 and the rear leg portion 168 disposed downward, the switch 200 can be kept in an off state, the electromagnet 180 can be brought close to the permanent magnet 151 without applying a current to the electromagnet 180, the rear leg portion 168 can be brought away from the front leg portion 149, and when the walking toy 100 is placed on a substantially horizontal walking surface 191, the lower end portion 215 of the switch movable body 210 can be brought into contact with the walking surface 191 as shown in fig. 6 (a).

Therefore, when the weight of the walking toy 100 is applied to the switch movable body 210 provided in the vicinity of the front end of the bottom plate 141 at the position of the front leg portion 149, the switch 200 is turned on, the electromagnet 180 is energized, and a repulsive force is generated between the electromagnet 180 and the permanent magnet 151.

Therefore, the electromagnet 180 is pushed forward, the rear leg portion 168 approaches the front leg portion 149 formed at the front end portion of the walking toy 100, and when the contact position of the rear leg portion 168 and the walking surface 191 is forward of the center of gravity position of the entire toy, as shown in fig. 6 (B), the front end portion of the walking toy 100 is lifted up and the front leg portion 149 is separated from the walking surface 191.

Therefore, when the switch 200 is turned off, the repulsive force between the electromagnet 180 and the permanent magnet 151 disappears, and the movable body 120 supported by the rocking plate 161 via the rocking pin is positioned behind the line connecting the contact point between the rear leg 168 and the traveling surface 191 and the rocking pin 133, and the center of gravity of the movable body 120, the housing 110, and the like is positioned in the forward direction with the rocking pin 133 as the center, and the center of gravity of the entire toy such as the movable body 120 is positioned in the forward direction with respect to the contact point, as shown in fig. 6 (a), the traveling toy 100 is tilted forward, the switch movable body 210 is brought into contact with the traveling surface 191, and the switch 200 is turned on.

Thus, the walking toy 100 can repeatedly switch the switch 200 between the on state and the off state to perform the walking forward, as in the conventional walking toy 100.

In the walking toy 100, the rocking contact plate 240 and the 2 nd wire guide plate 230 constituting the switch 200 are metal plates made of stainless steel or the like, the 2 nd wire guide plate 230 is fixed to the upper surface of the base plate 141, and the rocking contact plate 240 is positioned with the contact part 245 below the switch contact part 237 of the 2 nd wire guide plate 230, so that the rocking motion can be performed with the positions of the contact plate pressing part 135 and the auxiliary supporting protrusion 147 as the center, and the rocking contact plate is accommodated in the contact plate main body accommodating part 145 and the contact plate wrist accommodating part 146, the rear end of the rocking contact plate 240 is attracted and lifted by the permanent magnet 151, and the contact part 245 is slightly separated from the switch contact part 237, whereby the opening and closing operation of the switch 200 can be reliably performed_。

In addition, in the rocking contact plate 240, since the main body portion 241 is a metal plate such as stainless steel having a rectangular flat plate shape, the shape retention is strong, it is difficult to generate a difference between products, and it is easy to manufacture a product having a constant interval between the contact portion 245 and the switch contact portion 237_。

Further, since the contact portion 245 and the switch contact portion 237 are easily brought into contact due to a difference in manufacturing error, assembly error, or the like, the switch 200 can be turned on even when the walking toy 100 is assembled, for example, by the weight of the switch movable body 210 alone, and the distance between the upper end 244 of the vertical portion 243 of the rocking contact plate 240 and the permanent magnet 151 is adjusted to increase the force of attracting the rear end of the rocking contact plate 240 to the magnet, so that the contact between the contact portion 245 and the switch contact portion 237 is hardly generated.

That is, the distance between the permanent magnet 151 and the rear end of the rocking contact plate 240 is reduced by slightly shifting the permanent magnet 151 downward, or the front and rear end portions of the main body portion 241 of the rocking contact plate 240 are lifted upward, the main body portion 241 is slightly bent in a flexible manner, the upper end 244 of the vertical portion 243 is brought close to the permanent magnet 151 in a state where the front end of the main body portion 241 is in contact with the upper surface of the main body 211 of the switch movable body 210, and further, the support arm 247 is entirely bent so as to bring the front end of the support arm 247 of the rocking contact plate 240 downward, the position of the support arm 247 of the main body portion 241 is raised, and the upper end 244 of the vertical portion 243 is brought close to the permanent magnet 151 in a state where the front end of the main body portion 241 is in contact with the upper surface of. Thus, the vertical portion 243 of the rocking contact plate 240 approaches the permanent magnet 151, and the force for lifting the rear end of the rocking contact plate 240 can be increased.

Further, when the main body portion 241 of the rocking contact plate 240 is bent or the supporting arm portion 247 is bent, the long axis direction of the metal plate such as a plate-shaped rectangular stainless steel is set to a predetermined bent state, whereby the predetermined bent state can be adjusted very easily and in a short time as compared with the adjustment of the bending of the steel wire having elasticity, and the force required for bringing the contact portion 245 of the rocking contact plate 240 into contact with the switch contact portion 237 of the 2 nd lead plate 230 can be easily adjusted_。

Further, the position of the permanent magnet 151 fixed to the back plate 121 can be easily adjusted in an extremely short time. Therefore, the distance between the permanent magnet 151 and the upper end 244 of the vertical portion of the rocking contact plate 240 is adjusted, so that the force required for bringing the contact portion 245 of the rocking contact plate 240 into contact with the switch contact portion 237 of the 2 nd lead plate 230 can be easily adjusted, and the generation of defective products in which the battery 155 is consumed without end when not in use can be prevented.
