Document Type and Number:
Japanese Patent JP2015094392
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a linear actuator which can be flexibly adapted to different specifications, and is excellent in an assembling property, reliability, durability and a layout property while suppressing a cost increase.SOLUTION: Micro switches 11, 12 for detecting a position of a piston 7 are arranged, and on/off-operations of the switches are performed by the slide motion of a striker 14. When the piston 7 reaches a lower limit stop position L, an abutment protrusion 21 abuts on a first bent part 15a of a striker wire 15, the striker wire 15 is pulled to an A-direction, the striker 14 oscillates, and a switch press contact face 31a presses a switch button 11a. When the piston 7 reaches an upper limit stop position U, an end face 22a of a salient part 22 abuts on a second bent part 15b of the striker wire 15, the striker wire 15 is pulled to a B-direction, the striker 14 oscillates, and a switch press contact face 31b presses a switch button 12a.
