た。SUMMARY OF THE INVENTION In the conventional walker described above, however, an infant sitting on a seat accidentally tampered with the operation section to release the engagement of the engagement member from the rack. If this happens, the seat may be lowered while the infant is still sitting. Therefore, it is conceivable to install the operation part in a place where infants cannot reach, for example, in the center of the lower surface of the upper frame, but in that case, put your hand from the edge of the upper frame to the lower surface to find the operation part. Since it has to be done, there is a problem that it becomes difficult for the guardian to perform the height adjustment work.

Are supported by a pair of supporting rods pivotally supported, and the rear upper end of the supporting rod is rotatable with respect to the upper frame body, and the rear lower end is rotatable with respect to the base body, and the front upper end of the supporting rod is rotatable. To the upper frame, the front lower end is slidable forward and backward with respect to the base, respectively, and further, a rack in the front-back direction is provided at the front upper end of the support rod, and the upper frame is attached to the rack. The upper frame body by engaging and disengaging, and attaching an engaging member that is urged in the rack direction by the urging member to fix the sliding of the support rod, and moving the engaging position of the engaging member to the rack. The height position of the upper frame can be adjusted in stages, An operation lever for rotating the engagement member in a direction in which the engagement member is disengaged from the rack against the elasticity of the urging member, and a lock member for releasably locking the operation lever are provided on the surface, The operation direction of the operation lever is the front-back direction of the upper frame body, and the operation direction of the lock member is the left-right direction of the upper frame body.
