PROBLEM TO BE SOLVED: To provide a multipoint fastening lock device for a door for securing stable high sealing performance while reducing an operation point to one place. SOLUTION: An upper vertical support member 6 and a lower vertical support member 10 advances-retreats in the vertical direction by normal/ reverse rotation of a driving main shaft 11, and an upper horizontal support member 5 and a lower horizontal support member 9 simultaneously advances-retreats in the horizontal direction via an upper connector member 4 and a lower connector member 8 and upper crank levers 32 and 33 and lower crank levers 69 and 70 having respectively a delta plate shape so that a plurality of first lock members 15 engage with and disengage from an upper side horizontal edge part 17 of a casing 16, a plurality of second lock members 18 engage with and disengage from a vertical edge part 19 of the casing 16, a plurality of third lock members 20 engage with and disengage from a lower side horizontal edge part 21 of the casing 16 and a plurality of fourth lock members 22 engage with and disengage from the vertical edge part 19 of the casing 16, respectively without a time lag.
