Straddle type monorail vehicle and assembly method thereof

A straddle type monorail vehicle comprising:

• a vehicle body including a center pin fixed in a mode of being suspended from a bolster beam forming a floor portion;
• a bogie including a center pin holding portion into which a lower end portion of the center pin is inserted in order to support the vehicle body;
• and
• a fixing metal fitting, a lower metal fitting, and an upper metal fitting configured to fasten the center pin to the center pin holding portion, wherein
• the center pin has a hollow shape in which both ends are opened, and includes a large cylindrical portion on a bolster beam side and a small cylindrical portion that is connected to the large cylindrical portion and that is coaxial with the large cylindrical portion,
• the center pin holding portion is elastically supported by a bogie frame forming a frame body of the bogie, and has a hollow portion into which the small cylindrical portion of the center pin is inserted,
• the fixing metal fitting has a cylindrical rod shape inserted through the center pin, includes a first threaded portion at an upper end portion thereof, and includes a second threaded portion at a stepped portion formed at a lower end portion thereof,
• the lower metal fitting is disposed below the center pin holding portion, and has a female threaded hole to be threadedly engaged with the second threaded portion,
• the upper metal fitting is placed on an upper end surface of the center pin, and has a hole through which the first threaded portion penetrates, and
• in a state in which the second threaded portion is threadedly engaged with the female threaded hole and the lower metal fitting abuts against the stepped portion, the lower metal fitting is biased toward a lower end of the center pin and the upper metal fitting is biased toward an upper end of the center pin by threadedly engaging a nut with the first threaded portion that penetrates through the hole.
