The inner case includes a first frame arranged in the device case, a second frame arranged in parallel with the first frame in the device case, a coupling part configured to couple the first frame and the second frame, and a buffer member provided at the coupling part and configured to buffer shock to be applied to the first frame and the second frame. ## Claims ### Claim 1 A portable device comprising: a device case, and an inner case arranged in the device case, wherein the inner case comprises: a first frame arranged in the device case; a second frame arranged in parallel with the first frame in the device case in a depth direction of the inner case; a coupling member configured to couple the first frame and the second frame at a top of the first frame in the depth direction of the inner case so that a gap is formed between the first frame and the second frame; and a buffer member arranged to be fitted in the gap to fill the gap. ### Claim 2 (depends on 1) The portable device according to claim 1, wherein the first frame and the second frame have a rectangular shape respectively and are formed integrally with the coupling member. ### Claim 3 (depends on 1) The portable device according to claim 1, wherein a length of the second frame in a direction perpendicular to a coupling direction of the first frame and the second frame is coupled is smaller than a length of the first frame in the direction perpendicular to the coupling direction. ### Claim 4 (depends on 3) The portable device according to claim 3, wherein a length of the coupling member in the direction perpendicular to the coupling direction is substantially the same as the length of the second frame in the direction perpendicular to the coupling direction. ### Claim 5 (depends on 3) The portable device according to claim 3, wherein a length of the coupling member in the direction perpendicular to the coupling direction gradually decreases from both side end portions of the first frame in the direction perpendicular to the coupling direction towards both side end portions of the second frame in the direction perpendicular to the coupling direction. ### Claim 6 (depends on 1) The portable device according to claim 1, wherein the second frame is mounted with a component of which a weight is heavier than a weight of a component mounted to the first frame. ### Claim 7 (depends on 1) The portable device according to claim 1, wherein the second frame is mounted with a battery and the first frame is mounted with a display module. ### Claim 8 (depends on 1) The portable device according to claim 1, wherein the first frame, the second frame and the coupling member are formed of a first synthetic resin. ### Claim 9 (depends on 8) The portable device according to claim 8, wherein the first synthetic resin is an ABS resin or a composite material of PC resin and ABS resin. ### Claim 10 (depends on 8) The portable device according to claim 8, wherein the buffer member is formed of a second synthetic resin having higher resiliency than the first synthetic resin. ### Claim 11 (depends on 10) The portable device according to claim 10, wherein the second synthetic resin is a silicon resin or elastomer. ### Claim 12 (depends on 1) The portable device according to claim 1, wherein the coupling member has a slit-shaped fitting portion formed in a direction perpendicular to a coupling direction of the first frame and the second frame, and wherein the slit-shaped fitting portion defines the gap. ### Claim 13 (depends on 1) The portable device according to claim 1, wherein the buffer member is fitted in the gap so as to be pressed against the coupling member from a bottom side of the inner case. ### Claim 14 (depends on 1) The portable device according to claim 1, wherein the second frame is formed to be deeper than the first frame, and the second frame is coupled to the first frame by the coupling member so that a top of the second frame is higher than the top of the first frame in the depth direction of the inner case. ### Claim 15 A portable device comprising: an inner case of which first frame-shaped frame part and a second frame-shaped frame part are provided so that openings thereof are aligned in the same plane, a coupling member is formed to be thinner than a depth of the first frame-shaped frame part and a depth of the second frame-shaped frame part, wherein the coupling member is configured to couple the first frame-shaped frame part and the second frame-shaped frame part at a top of the first frame-shaped frame part in a depth direction of the inner case so that a gap is formed between the first frame-shaped frame part and the second frame-shaped frame part, and a buffer member arranged to be fitted in the gap to fill the gap. ### Claim 16 (depends on 1) The portable device according to claim 1, wherein the buffer member is in contact with a side surface of the first frame and a side surface of the second frame. ### Claim 17 (depends on 1) The portable device according to claim 1, wherein the buffer member is configured to buffer shock to be applied to the first frame and the second frame. ### Claim 18 (depends on 1) The portable device according to claim 1, wherein an end portion of the buffer member at bottom side is located at a bottom of the second frame in the depth direction of the inner case.
