  • Patent number: 6283438
    Abstract: A shock absorbing holder for holding a device vulnerable to an effect by shock so as to wrap it up and protect it against shock. The shock absorbing holder includes a frame body structured smaller than an outer shape of the device, a holding portion having a shape similar to the outer shape of the device defined by inner wall surfaces of the frame body, and protruding portions provided on outer surface walls of the frame body. With the frame body extended, the device is accommodated in the holding portion, being intimately contacted to the inner wall surfaces of the frame body. When shock is imported from outside, the protruding portions are deformed to absorb the shock, protecting the accommodated device from the shock.
