Publication number: 20170315324Abstract: A motor includes a vibrator, a mover guided by a guide member to move with the vibrator, and rollers sandwiched between the mover and the guide member. The mover includes first and second groove shapes formed along a moving direction of the vibrator to separate from each other. The guide member includes first and second guide parts opposite to the first and second groove shapes, respectively. The rollers are sandwiched among the first and second groove shapes, and the first and second guide parts. On a rear side of a surface of the guide member where the first and second guide parts are formed, the mover includes regulating parts regulating a movement of the guide member to the rear side. When the guide member abuts against the regulating parts, part of each of the rolling balls is positioned inside the first and second groove shapes.Type: ApplicationFiled: April 24, 2017Publication date: November 2, 2017Inventor: Kazuhiro Noguchi

Publication number: 20170315325Abstract: A vibration actuator that is capable of bringing a vibration body into pressure contact with a driven body stably during long time while reducing obstruction of excitation of vibration in the vibration body by the pressure force. The driven body is in contact with the vibration body by pressure force given by a pressing member. A vibration isolation member is arranged between the vibration body and the pressing member. The vibration body and the driven body move relatively by vibrations in first and second vibration modes that are excited in the vibration body by applying alternating voltage to a piezoelectric device on the vibration body. Face pressure that acts to the piezoelectric device by the pressure force from the pressing member in first and second areas that respectively include nodal lines in the first and second vibration modes and their vicinities is higher than that in the other area.Type: ApplicationFiled: April 12, 2017Publication date: November 2, 2017Inventors: Yuki Oda, Hiroyuki Seki
