To provide a landing shock absorber capable of smoothly reduce the landing shock caused when a leg body of a leg type mobile robot lands in a simple constitution.
The landing shock absorber 18 arranged in the sole mechanism 6 of the robot is provided with a bag-like member 19 (variable volume body) which can expand and compressed in relation to the landing face side of the sole mechanism 6. The bag-like member 19 is made of elastic material such as rubber so as to be restored. The inside of the bag-like member 19 communicates with an atmospheric side through a flow passage 20. When the leg body lands, the bag-like member 19 compressed to the land, and the inside air flows out to the atmosphere through the flow passage 20, generating flow resistance. This reduces landing shock. With the leg body separated from floor, the bag-like member 19 is expanded while making air flow into the inside by the restoring force of the bag-like member 19.
