PROBLEM TO BE SOLVED: To provide a movable bed which can detect a pinched foreign matter more reliably than a conventional movable bed.SOLUTION: On a rear face of a second movable mat support part 32 of a movable bed 1, a displacement part 81 is arranged for detecting contact of a foreign matter. The displacement part 81 can change an inclination angle integrally with the second movable mat support part 32 when the second movable support part 32 is inclined. The displacement part 81 is arranged while separated by a fixed distance from the rear face of the second movable mat support part 32. When a foreign matter comes into contact with the displacement part 81, the displacement part is displaced in a direction approaching the rear face of the second movable mat support part 32. When the displacement part 81 is displaced, a contact sensor 322 detects the displacement and a control part 6 controls a drive part 41 to reverse an inclination direction of the second movable mat support part 32.SELECTED DRAWING: Figure 3 |
