The board sealing device 1 comprises: a cover member 3 and a base member 4 that openably and closably store a junction board 2; and sealing parts 30, 40 that seal the respective members 3, 4 via a sealing pin 5 so as not to be opened and closed. The sealing parts 30, 40 include openings 311, 411, 412 in which the sealing pin 5 communicates insertably. The openings 411, 412 at a side of the base member 4 are disposed so as to sandwich the opening 311 at a side of the cover member 3. The sealing parts 30, 40 are formed at both the right and left edges of the respective members 3, 4. The sealing pin 5 is locked by each locking part 31b by push-in operation toward the inside from the outside of the device and along a nearly horizontal direction relative to the respective sealing parts 30, 40.
