Abstract:
A drive device comprises a housing (2) having a first connecting portion (C1), a drive portion (3), a spindle member (4) to rotate by driving of the drive portion (3), a nut member (5) screwed with the spindle member (4); and a moving member (6) coupled to the nut member (5), and has a rotation regulating portion (9) which suppresses rotation of the nut member (5) to move the nut member (5) in an axis X direction of the spindle member (4), wherein the moving member (6) has a second connecting portion (C2), and a fragile portion (61) to be broken by a predetermined force being weaker than a force required to break the nut member (5), and the fragile portion (61) is configured that a fracture portion (62) with which the nut member (5) is pressable by the moving member (6) toward the drive portion (3) is formable when the fragile portion (61) is broken. The drive device, which is connected to two base bodies, makes it possible to recognize an application of an excessive load without the drive device being separated from either one of the base bodies.
