PROBLEM TO BE SOLVED: To provide a lifting device for an X-ray photographing device, which can manually raise and lower a movable component such as a hand hold, an image receiving part, or the like while suppressing cost without adopting a complex configuration.SOLUTION: A lifting device for an X-ray photographing device comprises: a spring member 2 attached to a shaft member so as to be freely taken up and delivered; a slider 5 connected to the tip of the spring member; a support member connected to the slider; and a locking mechanism for fixing the position of the slider at a desired position. The locking mechanism comprises a locking latch 18 attached rotatably to the slider and having a locking claw part 19, and a rack 14 in which a plurality of locking grooves 15 for locking the locking claw part are formed. The locking latch is energized in a direction of locking the locking claw part to the locking groove. The lock state of the locking claw part to the locking groove is released by rotating the locking latch in an anti-energizing direction. When the locking claw part is locked to the locking groove, the slider is allowed to move in a direction of taking up the spring member and is prevented from moving in a direction of delivering the spring member.SELECTED DRAWING: Figure 1 |
