Abstract
A travel device includes a bogie frame (11) configured to support an axle (5) to which a wheel (3) is attached, a suspension frame (15) disposed close to a center of a vehicle body (1) with respect to the bogie frame (11) and having a support section (16) extending downward from the vehicle body (1), and an upper link (14a) and a lower link (14b) configured to connect the support section (16) and the bogie frame (11) to relatively move the bogie frame (11) with respect to the support section (16) in a vertical direction. In the lower link (14b), a position (11b) at which the lower link (14b) and the bogie frame (11) are connected by pin coupling is disposed lower than a position (15b) at which the lower link (14b) and the support section (16) are connected by pin coupling. In addition, even in the upper link (14a), similar to the lower link, a position (11a) at which the upper link (14a) and the bogie frame (11) are connected by pin coupling is disposed lower than a position (15a) at which the upper link (14a) and the support section (16) are connected by pin coupling. Thus, the lower link (14b) and the upper link (14a) are installed parallel to each other.
