(C) is a developed top view of the haptic transmission part shown in (a) or (b). The tactile transfer section shown in FIG. 5 (hereinafter referred to as “tactile transfer section 3C”) has the size of the flexible printed board 31 in the tactile transfer section 3B shown in FIG. The flexible printed circuit board 31 to which each of the linear actuators 33 is attached is pressed and attached by an attaching means composed of an elastic plate 40 such as a rubber plate. The elastic plate 40 has holes 4 through which the main body of each linear actuator 33 passes.
1 is provided, and each linear actuator 33
The main body of each linear actuator 33 is inserted into each hole 41 of this plate 40 from above, and the flexible printed circuit board 31 to which is attached is attached so that the lower surface of this flexible printed circuit board 31 comes into close contact with the upper surface of this plate 40. Further, the movable shaft 34 of each Riyani actuator 33 and the ring-shaped projection 39 are pressed and fixed by an elastic fixing plate having a hole 43 penetrating therethrough. When the elastic plate 40 is formed into a ring shape and fitted on the operator's finger 9, the elasticity of the plate 40 allows the linear actuators 33 to be in close contact with the operator's finger 9.
