TRUCK STRUCTURE OF SKATEBOARD

WIPO Patent Application WO/2021/137273

A1

[Problem] To allow the longitudinal direction of a pivot shaft to be borne by cylindrical needle bearings and allow a steering operation carried out through shifting of body weight to be smoothly performed with respect to a truck structure of a skateboard. [Solution] The present invention is characterized in that: an upper through-hole is provided in a support base, the upper through-hole being such that the lower end thereof opens on an upper-side sliding surface, and being such that an upper part of a pivot shaft is inserted therethrough; a lower through-hole is provided in a rockable part coaxially with the upper through-hole, the lower through-hole being such that the upper end thereof opens adjacent to the upper-side sliding surface, and being such that a lower part of the pivot shaft is inserted therethrough; a large-diameter hole section is provided in the lower through-hole, the large-diameter hole section accommodating cylindrical needle bearings that are externally fitted at least onto a lower shaft part; and the lower shaft part of the pivot shaft is borne by the cylindrical needle bearings.
