1. A snow guard structure including a snow guard fitting which is mounted on roof on which solar cell panels are installed, wherein a first frame body holding a ridge-side end side of the solar cell panel arranged at an eaves side in the solar cell panels arranged adjacently on the roof and a second frame body holding an eaves-side end side of the solar cell panel arranged at a ridge side are fixed onto a roof surface such that spaces are formed under bottom face portions of the first frame body and the second frame body, andthe snow guard fitting includes:an upper abutment piece having a first upper abutment portion abutting against an upper face portion of the first frame body at one end side, a second upper abutment portion abutting against an upper face portion of the second frame body at the other end side, and an upper connecting portion connecting the first upper abutment portion and the second upper abutment portion;a lower abutment piece having a first lower abutment portion abutting against a bottom face portion of the first frame body at one end side, a second lower abutment portion abutting against a bottom face portion of the second frame body at the other end side, and a lower connecting portion connecting the first lower abutment portion and the second lower abutment portion, the lower connecting portion further including a connecting intermediate portion located at a position higher than the first lower abutment portion and the second lower abutment portion, a first inclined wall inclined from the connecting intermediate portion toward the first lower abutment portion, and a second inclined wall inclined from the connecting intermediate portion toward the second lower abutment portion, the lower abutment piece having an outer shape of a parallelogram in planar view, wherein a distance L1 between a pair of lateral sides, each of which extends in the direction toward the second lower abutment portion from the first lower abutment portion, is smaller than an inter-frame body distance between the first frame body and the second frame body while a distance L2 between a boundary line B1 and a boundary line B2 is smaller than the inter-frame body distance, wherein the boundary line B1 is the boundary line between the first lower abutment portion and the first inclined wall while the boundary line B2 is the boundary line between the second lower abutment portion and the second inclined wall;an external thread member extending upward from the lower abutment piece and penetrating through the upper abutment piece such that the upper abutment piece and the lower abutment piece are fastened, and an external thread formed on an outer circumferential surface is screwed in with an internal thread between the first frame body and the second frame body, wherein as the lower abutment piece is configured to rotate as the external thread member is rotated, the first lower abutment portion engages with the bottom face portion of the first frame body as being guided by the first inclined wall while the second lower abutment portion engages with the bottom face portion of the second frame body as being guided by the second inclined wall;and a snow guard portion extending upward from the upper abutment piece to be higher than upper face portions of the first frame body and the second frame body. 2. A snow guard structure including a snow guard fitting which is mounted on roof on which solar cell panels are installed, wherein a first frame body holding a ridge-side end side of the solar cell panel arranged at an eaves side in the solar cell panels arranged adjacently on the roof and a second frame body holding an eaves-side end side of the solar cell panel arranged at a ridge side are fixed onto a roof surface such that spaces are formed under bottom face portions of the first frame body and the second frame body, andthe snow guard fitting includes:an upper abutment piece having a first upper abutment portion abutting against an upper face portion of the first frame body at one end side, a second upper abutment portion abutting against an upper face portion of the second frame body at the other end side, and an upper connecting portion connecting the first upper abutment portion and the second upper abutment portion and having a through-hole;a lower abutment piece having a first lower abutment portion abutting against a bottom face portion of the first frame body at one end side, a second lower abutment portion abutting against a bottom face portion of the second frame body at the other end side, and a lower connecting portion connecting the first lower abutment portion and the second lower abutment portion and having a non-circular through-hole, the lower connecting portion further including a first inclined wall inclined from a connecting intermediate portion toward the first lower abutment portion, and a second inclined wall inclined from the connecting intermediate portion toward the second lower abutment portion, the lower abutment piece having an outer shape of a parallelogram in planar view;an external thread member having a head portion that is larger than the non-circular through-hole and a non-circular root portion in a corresponding non-circular columnar shape that is integrally formed with the head portion, the external thread member extending upward from the lower abutment piece through the non-circular through-hole with the non-circular root portion engaged in the non-circular through-hole and penetrating through the upper abutment piece through the through-hole and fastening the upper abutment piece and the lower abutment piece by screwing an external thread formed on an outer circumferential surface with an internal thread between the first frame body and the second frame body, wherein the lower abutment piece is configured to rotate guided by the first inclined wall and the second inclined wall as the external thread member is rotated; anda snow guard portion extending upward from the upper abutment piece to be higher than upper face portions of the first frame body and the second frame body. 3. The snow guard structure according to claim 2, wherein the lower abutment piece of the snow guard fitting has a maximum length between a pair of lateral sides, each of which extends in a direction toward the second lower abutment portion from the first lower abutment portion, is the maximum length being smaller than a space between the first frame body and the second frame body. 4. The snow guard structure according to claim 2, wherein the upper connecting portion of the snow guard fitting has a first lateral face abutment portion extending downward from the first upper abutment portion and abutting against a lateral face portion of the first frame body, a second lateral face abutment portion extending downward from the second upper abutment portion and abutting against a lateral face portion of the second frame body, and a connecting intermediate portion connecting the first lateral face abutment portion and the second lateral face abutment portion.
