The invention relates to the technical field of elevators, and discloses a buffer with a one-way buffer tube structure and an elevator, and the buffer comprises a buffer oil cylinder, a one-way buffer tube and a buffer device. The buffering oil cylinder comprises a cylinder body provided with a piston and a buffering pressing rod connected to the piston, the cylinder body is provided with a buffering cavity used for containing hydraulic oil, the buffering pressing rod can drive the piston to do reciprocating stretching and retracting movement relative to the cylinder body, and the cylinder body is further provided with an oil conveying hole communicated with the buffering cavity. The one-way buffer pipe is provided with a buffer inlet and a buffer outlet, and the buffer inlet is communicated with the oil conveying hole; the buffering device comprises a buffering cavity, the buffering cavity communicates with the buffering outlet, and the buffering cavity is used for buffering hydraulic oil flowing out through the oil conveying hole and the one-way buffering pipe. The anti-falling device is not prone to aging, good in universality and capable of absorbing instantaneous impact force generated when the lift car falls to the ground, and damage of the impact force to the lift car is reduced.
