摘要： A door latch device (10) includes a motor (94), a mechanical mechanism (38), a door lock ECU (2), and a case (20). The door lock ECU (2) includes a printed wiring board (120) and a capacitor (202) connected to the printed wiring board (120). The case (20) includes a bottom plate (122b), a first accommodation space (36) for accommodating the motor (94) and the mechanical mechanism (38) on one side of the bottom plate (122b), and a second accommodation space (124) for accommodating the printed wiring board (120) and the capacitor (202) on the other side of the bottom plate (122b). The bottom plate (122b) is provided with a capacitor accommodation portion (125) recessed from the second accommodation space (124) toward the first accommodation space (36) and the capacitor (202) is arranged in the capacitor accommodation portion (125).

摘要： An operation of a detection target is more securely detected. A door latch device includes: a first switch 106 and a second switch 108 in which a first contact hole 200a connected to a normally open contact, a second contact hole 200b connected to a normally closed contact, and a common contact hole 200c connected to a common contact are arranged in the X-direction, the first switch 106 and the second switch 108 being disposed and stacked at positions shifted from each other in the X-direction; a common pin 130c inserted into the common contact hole 200c of the first switch 106 and a first contact hole 200a of the second switch 108 to be conducted; a first signal pin 130a inserted into the first contact hole 200a of the first switch 106 to be conducted; and a second signal pin 130b inserted into the common contact hole 200c of the second switch 108 to be conducted. The first switch 106 and the second switch 108 perform a switch operation at the same timing due to an operation of an operation detection target.
