In view of the load that the wheel 30 receives from the swing part 40 , when the frictional force is small, there is apprehension that the wheel 30 slides and stops rotating on the traveling surface 1 , and as a result, the swing part 40 is no more able to swing.
  • the traveling surface 1 is a slippery surface, such as a table surface or a floor surface
  • the material of the wheel 30 needs to be determined by taking both the weight and frictional force caused between the wheel 30 and the contact surface into account.
  • the wheel 30 is formed of brass and the contact surface is processed so as to have a moderate surface roughness, this is a mere example and as described above, the material of the wheel is desirably determined by taking both the weight and frictional force caused between the wheel and the contact surface into account.

  • the external force large enough to move the toy body 20 in the directions A 2 and B 2 that cross the traveling direction D 1 can easily act on the wheel 30 , that is, the toy body 20 can easily be energized in the directions A 2 and B 2 that cross the traveling direction D 1 and the toy body 20 can easily move, or easily tilts in the present embodiment.
  • a radius r of the wheel 30 may be determined by the relation with the weight of the swing part 40 and the travel distance per 360-degree turn of the wheel 30 .
  • the wheel 30 is desirably made as large as possible, if the wheel 30 is too heavy, the total weight of the manual traveling toy 10 is too large and the external force applied from the swing part 40 , that is, the energization by the swing part 40 might fail to move the manual traveling toy 10 in the direction A 2 or B 2 so an upper limit of the radius r is set in relation to the weight of the wheel 30 .
  • the width W of the wheel 30 may be made small so as to increase the radius r of the wheel 30 and reduce the weight of the wheel 30 , a lower limit of the width W is also set so as to ensure stability in the sideward swing during the travel.

  • the travel distance per 360-degree turn of the wheel 30 can be indicated as 2 ⁇ r.
  • the swing part 40 is swung in the directions A 1 and B 1 and performs one cycle of to-and-fro movement.

  • the radius r of the wheel 30 is set so as to be larger than or equal to 9 mm and the travel distance 2 ⁇ r is set so as to be larger than or equal to at least 56.5 mm so that the toy body 20 moves, or tilts in the present embodiment, to perform one cycle of to-and-fro movement in the directions A 2 and B 2 .
  • increasing the radius r of the wheel is advantageous because the increase raises the position of the center of gravity of the wheel 30 and facilitates the tilt of the toy body 20 in the directions A 2 and B 2 .
  • FIGS. 7A and 7B A variation of the rotation-swing converting mechanism 50 A is described with reference to FIGS. 7A and 7B .
  • the eccentric cam 51 A illustrated in FIG. 7B may be arranged between the two wheels 31 and part of the rotation-swing converting mechanism 50 A that includes the eccentric cam 51 A may be arranged between the two wheels 31 .
