A waterproofing case with a first case and a second case includes a non-annular groove that has a start point side and an end point side and is arranged in parallel by a barrier rib of a certain length, in one of annular bonding portions. The waterproofing case also includes a cutout portion provided at a middle portion of the barrier rib so as to allow a groove portion at the start point side and the end point side to communicate with each other and a plastic elastomer that is disposed within the non-annular groove by curing after being coated. Furthermore, the waterproofing case includes a protrusion that bisects an exposed portion of the plastic elastomer disposed within the non-annular groove toward opposite walls of the non-annular groove at bonding two cases, in other annular bonding portion of the first case and the second case.

1. A waterproofing case that has a first case and a second case each including an annular bonding portion, the waterproofing case comprising: a non-annular groove, located in one of annular bonding portions of the first case and the second case, that has a start point side and an end point side arranged in parallel by a barrier rib of a certain length, wherein the barrier rib is arranged in parallel to the start point side and in parallel to the end point side;a cutout portion that is provided at a middle portion of the barrier rib so as to allow a groove portion at the start point side and a groove portion at the end point side to communicate with each other;a plastic elastomer that is disposed within the non-annular groove by curing after being coated, wherein the plastic elastomer has a first distinct free end at the start point side of the non-annular groove, and the plastic elastomer has a second distinct free end at the end point side of the non-annular groove; anda protrusion, located in the other annular bonding portion of the first case or the second case, that does not arrive at a bottom of the non-annular groove and bisects an exposed portion of the plastic elastomer disposed within the non-annular groove, moving the plastic elastomer toward opposite walls of the non-annular groove when the first case and the second case are bonded to each other,wherein the protrusion is continued to cross the barrier rib at a position of the cutout portion. 2. The waterproofing case according to claim 1, wherein a width and height of the protrusion are uniform over the entire perimeter thereof, and a bottom of the cutout portion has a depth that produces a gap between a position of a tip end of the protrusion and the bottom of the cutout portion and is positioned higher than the bottom of the non-annular groove. 3. The waterproofing case according to claim 2, wherein the bottom of the cutout portion and the bottom of the non-annular groove are continued by a curved surface. 4. The waterproofing case according to claim 1, wherein the non-annular groove has a rectangular cross-sectional shape. 5. The waterproofing case according to claim 4, wherein the bottom and walls of the non-annular groove are connected at curved surfaces. 6. The waterproofing case according to claim 1, wherein a tip end of the protrusion has a rectangular cross-sectional shape. 7. The waterproofing case according to claim 1, wherein a tip end of the protrusion has a curved cross-sectional shape. 8. The waterproofing case according to claim 1, wherein one of the start point side and the end point side of the non-annular groove is positioned inside of the waterproofing case. 9. A waterproofing case that has a first case and a second case each including an annular bonding portion, the waterproofing case comprising: an outer wall, located in an end surface of one of the annular bonding portions of the first case and the second case, that is provided with a certain height over the entire perimeter thereof;parallel grooves that are formed at a certain position inside the outer wall by a barrier rib and an inner wall which have the same height as the outer wall, wherein the barrier rib is arranged in parallel to the parallel grooves;a cutout portion provided at a middle portion of the barrier rib so as to allow one of the parallel grooves to communicate with the other parallel groove, the parallel grooves being closed by end wall positions where an adjacent relationship there-between is terminated, respectively;a plastic elastomer that is cured after coating is disposed on an inner end surface of and bottoms of the parallel grooves using one end wall of the parallel grooves as a start point and other end wall as an end point, wherein the plastic elastomer has a first distinct free end at one end of one parallel groove, and the plastic elastomer has a second distinct free end at an end of another parallel groove; anda linear protrusion, located in an end surface of the annular bonding portion of the other first case and the second case, that when the first case and the second case are bonded to each other, does not arrive at the end surface adjacent to the end wall and longitudinally bisects an exposed portion of the plastic elastomer,wherein the linear protrusion is continued to cross the barrier rib at the position of the cutout portion. 10. The waterproofing case according to claim 1, wherein the plastic elastomer is converted into a liquid phase to have a high fluidity when heated before coating, and cured to an elastic body that has adhesiveness, and does not flow when cooled to a temperature not higher than a melting point thereof. 11. The waterproofing case according to claim 1, wherein the plastic elastomer is in a liquid phase before coating and is cured to an elastic body which has adhesiveness, and does not flow after coating when a plurality of components are mixed thereto during coating. 12. The waterproofing case according to claim 1, wherein the plastic elastomer is in a liquid phase before coating and is converted into an elastic body by reacting with moisture in the air after coating. 13. The waterproofing case according to claim 1, wherein the plastic elastomer is in a liquid phase before coating and is converted into an elastic body by reacting with light such as ultraviolet rays irradiated after coating. 14. The waterproofing case according to claim 1, wherein the plastic elastomer is in a liquid phase before coating and is converted into an elastic body by reacting with heat applied after coating. 15. A method of manufacturing a waterproofing case, comprising: providing a first case and a second case each including an annular bonding portion;providing a non-annular groove, in one of annular bonding portions of the first case and the second case, having a start point side groove and an end point side groove;wherein the start point side groove and the end point side groove are provided in parallel to each other by a barrier rib having a certain length, and the barrier rib is arranged in parallel to the start point side groove and in parallel to the end point side groove;providing a cutout portion at a middle portion of the barrier rib to allow the start point side groove and the end point side groove to communicate with each other; andproviding, on the annular bonding portions of the other of the first case and the second case, a linear protrusion that does not arrive at an end surface adjacent to an end wall and longitudinally bisects an exposed portion of a plastic elastomer disposed within the non-annular groove when the first case and the second case are bonded to each other, wherein the plastic elastomer has a first distinct free end at the start point side groove, and the plastic elastomer has a second distinct free end of the end point side groove,wherein the linear protrusion is continued to cross the barrier rib at the position of the cutout portion and the plastic elastomer is cured after coating to have elasticity.
