Boarding and exiting handrail

A boarding and exiting handrail, comprising:

• a base part provided near an entrance-and-exit of a vehicle so as to be rotatable with an axis oriented in a vehicle body up-down direction;
• a handrail main part provided on the base part and capable of being gripped by passengers boarding and exiting through the entrance-and-exit;
• and
• a rail part provided on the base part and slidably holding a sliding member mounted on a sliding door that opens and closes the entrance-and-exit by moving along an outer wall surface of the vehicle, wherein
• when the sliding door opens the entrance-and-exit, the sliding member slides along the rail part toward the base part so as to bring the boarding and exiting handrail into a deployed posture with the handrail main part and the rail part protruded toward an outside of the vehicle as seen from above, and when the sliding door closes the entrance-and-exit, the sliding member slides along the rail part toward the opposite side from the base part so as to bring the boarding and exiting handrail into a retracted posture with the handrail main part and the rail part disposed along the sliding door as seen from above.
