Patent number: 9196442Abstract: A contact point device 1 includes a drive block 2 that has a drive shaft 25 to which a movable contactor 29 is attached, and drives the movable contactor 29. The movable contactor 29 is attached to the drive shaft 25 so as to be movable relatively to the drive shaft 25 in an axial direction of the drive shaft, and in addition, relative movement thereof in the axial direction is regulated due to abutment of the movable contactor 29 against a regulating portion 60. Then, between the movable contactor 29 and the regulating portion 60 is formed a rotational movement deregulating portion 80, which relaxes the regulation by the regulating portion 60 for the relative rotational movement of the movable contactor 29 in the axial direction.Type: GrantFiled: December 26, 2013Date of Patent: November 24, 2015Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Masahiro Ito, Tsukasa Nishimura
