PROBLEM TO BE SOLVED: To simplify the structure of a work inclination device and perform an inclined rising operation required for the machining of a work smoothly and surely. ;SOLUTION: A lifter 30 is supported rotatably by the plunger of a cylinder 40 and a supporting member 20. Also the plunger is extended to raise the lifter 30 to its upper limit in order to push up and incline a work by a push-up part 34. During the rising, first the lifter 30 rises in upright position while a guide roller 32 moves a first guide part 52a upward so as to push up the work W. Next, when the guide roller 32 is directed by a flapper 71 and raised along a second guide part 52b1, the lifter 30 increases its inclination angle gradually. Then, when the lifter 30 rises along a third guide part 52c1, it rises under the condition that a specified inclination angle is maintained. By merely raising the lifter 30 along the guide part 52, the work can be raised under inclined condition.;COPYRIGHT: (C)1999,JPO
