## Abstract

A personal mobility includes a steering shaft, a handlebar extending from an upper end of the steering shaft to opposite sides, two grip parts installed on opposite ends of the handlebar, respectively, to be displaceable with respect to the handlebar in a direction of intersecting a longitudinal direction of the handlebar, and a buffer device provided between each of the grip parts and the handlebar to reduce vibration or shock transmitted from the handlebar to the grip part.

## Claims

### Claim 1

A personal mobility comprising:
a steering shaft;
a handlebar extending from an upper end of the steering shaft to opposite ends of the handlebar;
each end of the handlebar includes:
a grip part positioned on the end of the handlebar and being displaceable with respect to the handlebar in a direction intersecting a longitudinal direction of the handlebar;
a support plate attached to the end of the handlebar by a screw engaging a threaded bore in the end of the handlebar;
at least one buffer device provided between the grip part and the handlebar to reduce vibration or shock transmitted from the handlebar to the grip part;
the at least one buffer device further comprises one or more gas dampers interposed between an outer surface of the handlebar and an inner surface of the grip part in the displacement direction;
wherein the one or more gas dampers include:
a cylinder; and
a piston coupled to the cylinder, the piston configured to be moveable forward and backward, and being fixed to the inner surface of the grip part.

### Claim 2 (depends on 1)

The personal mobility according to claim 1, wherein each grip part is limited in rotation and longitudinal displacement with respect to the handlebar.

### Claim 3 (depends on 2)

The personal mobility according to claim 2, wherein each at least one buffer device comprises a plurality of springs interposed between the outer surface of the handlebar and the inner surface of the grip part in the displacement direction, and the plurality of springs are spaced apart from each other in a longitudinal direction of the grip part.

### Claim 4 (depends on 2)

The personal mobility according to claim 2, wherein each one or more gas dampers includes a plurality of gas dampers interposed between the outer surface of the handlebar, the plurality of gas dampers are symmetrically positioned on opposite sides of a grip part coupling part of the end of the handlebar.

### Claim 5 (depends on 1)

The personal mobility according to claim 1, wherein the handlebar is rotatably coupled to the upper end of the steering shaft.

### Claim 6 (depends on 1)

The personal mobility according to claim 1, wherein each end further comprises:
a grip part coupling part;
the grip part comprising a coupling groove having a rectangular cross-section coupled to the outside of the grip part coupling part;
the coupling groove comprises a width in a first direction corresponding to a width of the grip part coupling part in the first direction, and a width in a second direction of intersecting the first direction being greater than a width of the grip part coupling part in the second direction.
