Abstract: A backpack type assembly may include a backpack type carrier configured to be worn by a user and a device configured to be attached to the backpack type carrier. The backpack type carrier may include a pair of shoulder straps configured to be worn on both shoulders of the user, a back plate to which the pair of shoulder straps and the device are attached, a waist belt configured to be wrapped around a waist of the user, and a connection mechanism configured to connect between the back plate and the waist belt. The connection mechanism may include an elastic member having a flexural rigidity smaller than a flexural rigidity of the back plate. A force applied to the connection mechanism from one of the back plate and the waist belt may be transmitted through the elastic member to the other of the back plate and the waist belt.
