Abstract

PURPOSE: To miniturize the structure while a small sharp turn is enabling, by means of arranging a case of a front wheel of a specified constitution freely from rotation at the lower part of the conductive case of the end part of the front axis body.
CONSTITUTION: A connecting member 24 is formed in one body at the lower part of a conductive case 22 which is formed in one body at both ends of a front wheel axis body 8 laid by a driving axis 1, and a front wheel case 23 conprising of a bearing case 10 supporting a front wheel axis 2 by bearings and a conducting case (9), is connected to upper and lower kingpins 30, 31 of the conductive case 22 via bearings of the kingpins 17,18 and a bearing of a thrust 16 around a middle power conductive axis 7 having a longitudinal axis center freely from rotation. By such means, the front wheel case 23 is able to be moved as a center in the axis center around the longitudinal axis having in common with the power conductive system, thereby a small sharp turn becomes able, even if the diameter of a fixed bevel gear 6 at the front wheel mounting axis 2 becomes large, the gear is contained in a conductive case 9 without increasing the interval between the axis center of a driving axis 1 and the front wheel mounting axis 2, and the lengths to up and down directions of both case 22, 23 is shortened.
