The present disclosure aims to suppress heat generation of a single-phase diode bridge itself and a pattern directly below the same in a case where the single-phase diode bridge is used instead of a three-phase inverter mounted on a three-phase four-wire 400V air conditioner. A power generation device (100) includes a first inverter (20A) and a second inverter (20B) mounted on a printed wiring board (10). The first inverter (20A) includes a first diode bridge (21Aa) and a second diode bridge (21Ab) that convert alternating-current power into direct-current power, the first diode bridge (21Aa) being connected between a first wiring (11) connected to an R phase and a second wiring (12) connected to an S phase, and the second diode bridge (21Ab) being connected between the second wiring (12) and a third wiring (13) connected to a T phase. The second inverter (20B) includes a third diode bridge (21B) connected between a fourth wiring (14) connected to an N phase and a fifth wiring (15) branched from the first wiring (11) that converts alternating-current power into direct-current power.

The present invention provides a connector (6) that facilitates the operation of connecting the connector to the zipper head body and the movable body of the guide rail unit, or the pre-operation for preparing the guide rail unit, etc. The connector (6) connects the guide rail unit (1) and the zipper (5). The guide rail unit (1) includes: a base (2) in which an object is disposed with the X direction as the guiding direction and separated in the Z direction; and a movable body (3) which is guided relative to the base in the X direction and is used to mount the object. The zipper (5) includes: a pair of toothed chain straps (51) which are opposed on both sides of the movable body in the Y direction between the object and the base; and a zipper head body (52) which opens and closes the pair of toothed chain straps (51) in the X direction. The connectors are provided as separate parts: a connector (7) for the zipper head, which is connected to the zipper head body; and a connector (8) for the movable body, which is connected to the movable body. One of the connectors for the zipper head and the connector for the movable body is a socket (8), and the other is a pin (7) that can be installed and removed by plugging and unplugging relative to the socket (8).
