1. An electric mobility vehicle comprising:
a front-wheel-side body including a front wheel;
a rear-wheel-side body including a rear wheel;
a seat on which a passenger sits in an in-use state; and
a linking mechanism that links the front-wheel-side body with the rear-wheel-side body so as to be pivotable about a pivoting axis extending in a vehicle width direction, wherein
the electric mobility vehicle is foldable by employing an X-shaped frame with which a folded state is achieved by pivoting the front-wheel-side body and the rear-wheel-side body relative to each other in a vehicle front-to-rear direction so that the front wheel and the rear wheel are brought close to each other,
the electric mobility vehicle includes:
a footrest which is provided in the front-wheel-side body and on which the passenger on the seat places his/her feet,
a front-end roller or a front-end caster provided in the front-wheel-side body and disposed at a vehicle front side of the electric mobility vehicle relative to a front end of the front wheel in the in-use state, wherein the front-end roller or the front-end caster does not come into contact with a floor surface in the in-use state, and
wherein the front-end roller or the front-end caster comes into contact with the floor surface in the folded state to make the electric mobility vehicle stand alone,
wherein the seat is supported by a seat support portion constituted by a portion of the front-wheel-side body, and the pivoting axis is disposed at a position at which the pivoting axis passes through the seat support portion or in a vicinity of the seat support portion, and thereby the front-wheel-side body and the rear-wheel-side body take substantially an X-shape when viewed from the vehicle width direction.
