PROBLEM TO BE SOLVED: To provide a walking aid stick reducing an influence of reaction force on an arm, when being used as an aid of walking, preliminarily reducing own peculiar use method, and being used by naturally bending the elbow.SOLUTION: The walking aid stick includes: a stick root part 13 comprising a straight extension part, and an inclined straight-extension part having an angle with respect to the straight extension part a grip member 10 fitted and fixed to the inclined straight-extension part a forearm support part 12 fitted to the straight extension part and/or the inclined straight-extension part and a sick tip end 17 vertically-adjustably positioned in the stick root part. An angle formed between a forearm placement surface of the forearm support member and the inclined straight-extension part is within a range of 110±10°, and both of an angle formed between the straight extension part and the inclined straight-extension part, and an angle formed between the forearm placement surface and the straight extension part are obtuse angles.SELECTED DRAWING: Figure 1
