Abstract: A heavy article inversion device is provided, in which the inverting operations may be performed in a short time by reducing the size of the heavy article inversion device comprising a pair of inversion boards that may be revolved about a common rotary shaft supported in the center of a base between the horizontal state and the angles of revolution of less than 180 degrees from the horizontal state, and a pair of cam plates each fixed to the corresponding one of the pair of inversion boards and having its proximal end side rotatably fixed to the common rotary shaft, in which each one of the pair of cam plates has a curved lower outer circumferential surface extending from the proximal end side toward the radial outside end and which may be engaged by the rod of each respective one of the pair of linear drive mechanisms when the rod is being moved out of and moved back into the corresponding cylinder of the respective liner drive mechanism, thereby causing the respective cam plate to be rotated about the commo

Abstract: A joystick type switch device is provided that includes an operating shaft having an operating knob provided at one end, and a case supporting the operating shaft so that the operating shaft can move between a return position and a pushed-in position and tilt from a neutral position around a tilt center, it being possible to detect pushing of the operating shaft into the pushed-in position and tilting of the operating shaft from the neutral position into eight directions, wherein the operating shaft (16) has a magnet mounted at the other end, and a portion, facing the magnet, of a base plate (22) mounted on the case has at least three Hall elements (43A to 43D) fixed thereto at equal intervals around the axis of the operating shaft (16) in the neutral position. This enables excellent durability to be obtained and the number of components to be reduced.
