To solve the problem of fatigue caused by shouldering or holding baggage or a child for a long period of time and, especially in the case of mountaineering, a risk of heat attack caused by injury or hyperhidrosis caused by loss of concentration because of necessity of enduring shouldering heavy baggage to a destination in addition to great fatigue.SOLUTION: An assisting rucksack is invented which converts downward gravitational force of shouldered or held baggage or a child to force in a direction for pushing the spine to assist muscle force continuously raising the upper body. Tight fixation of baggage to the back's upper part, both shoulders, and both sides reduces loss of the force pushing the spine and positions the baggage at a point near the body higher than the center of gravity, which makes the baggage be felt lighter in weight.SELECTED DRAWING: Figure 1
