Lower fastening sections are disposed at positions below a battery cell and projects in the row direction beyond the battery cell arrayed body of the lower layer, and join the lower holding frame member and the middle holding frame member with each other by fastening. ## Claims ### Claim 1 A cell block of at least two battery cell arrayed bodies configured by disposing cylindrical battery cells in parallel, and the at least two battery cell arrayed bodies by at least three holding frame members in a stacking direction of the battery cell arrayed bodies, the cell block comprising: holding sections that hold a battery cell arrayed body of a lower layer between a lower holding frame member and a middle holding frame member, hold a battery cell arrayed body of the upper layer between the middle holding frame member and an upper holding frame member, and hold the battery cell arrayed body of the upper layer and the battery cell arrayed body of the lower layer displaced from each other in a row direction; lower fastening sections that are disposed at positions below a battery cell that projects to one side in the row direction beyond the battery cell arrayed body of the lower layer out of battery cells composing the battery cell arrayed body of the upper layer, and joining the lower holding frame member and the middle holding frame member with each other by fastening; and upper fastening sections that are disposed at positions above a battery cell that projects to one side in the row direction beyond an upper layer battery cell arrayed body of battery cells composing a lower layer battery cell arrayed body, and joining the middle holding frame member and the upper holding frame member with each other by fastening. ### Claim 2 (depends on 1) The cell block according to claim 1, wherein the lower fastening sections comprise lower fastening screws attached from above the middle holding frame member so that the middle holding frame member is overlaid on top of the lower holding frame member, and wherein the upper fastening sections comprise upper fastening screws attached from above the upper holding frame member in a state the upper holding frame member is overlaid on top of the middle holding frame member. ### Claim 3 (depends on 1) The cell block according to claim 1, further comprising: lower locking sections that are disposed at both side positions in a lateral width direction of the lower layer battery cell arrayed body and joining the lower holding frame member and the middle holding frame member to each other by locking; and upper locking sections that are disposed at both side positions in a lateral width direction of the upper layer battery cell arrayed body and joining the middle holding frame member and the upper holding frame member each other by locking. ### Claim 4 (depends on 3) The cell block according to claim 3, wherein the lower locking sections join the lower holding frame member and the middle holding frame member to each other by inserting locking claws that project from one of the lower holding frame member and the middle holding frame member toward the other along the stacking direction into locking holes arranged in the other of the lower holding frame member and the middle holding frame member for locking; and wherein the upper locking sections join the middle holding frame member and the upper holding frame member to each other by inserting locking claws that project from one of the middle holding frame member and the upper holding frame member toward the other along the stacking direction into locking holes arranged in the other of the middle holding frame member and the upper holding frame member for locking. ### Claim 5 (depends on 2) The cell block according to claim 2, further comprising: lower locking sections that are disposed at both side positions in the lateral width direction of the lower layer battery cell arrayed body and join the lower holding frame member and the middle holding frame member to each other by locking; and upper locking sections that are disposed at both side positions in a lateral width direction of the upper layer battery cell arrayed body and join the middle holding frame member and the upper holding frame member to each other by locking. ### Claim 6 (depends on 5) The cell block according to claim 5, wherein the lower locking sections join the lower holding frame member and the middle holding frame member to each other by inserting locking claws that project from one of the lower holding frame member and the middle holding frame member toward the other along the stacking direction into locking holes arranged in the other of the lower holding frame member and the middle holding frame member for locking; and wherein the upper locking sections join the middle holding frame member and the upper holding frame member to each other by inserting locking claws that project from one of the middle holding frame member and the upper holding frame member toward the other along the stacking direction into locking holes arranged in the other of the middle holding frame member and the upper holding frame member for locking.
