It may mean that the size of the stopper 32 of the first support shaft 29 is larger than the size of the shaft body 31 of the first support shaft 29 in the radial direction of the first support shaft 29. It may also mean that the size of the stopper 32 of the second support shaft 30 is larger than the size of the shaft body 31 of the second support shaft 30 in the radial direction of the second support shaft 30. The shaft body 31 of the first support shaft 29 passes through the first locking member 19, and the first locking member 19 is clamped between the limiting portion 32 of the first support shaft 29 and the housing 17. This limits the position of the first locking member 19. The shaft body 31 of the second support shaft 30 passes through the second locking member 20, and the second locking member 20 is clamped between the limiting portion 32 of the second support shaft 30 and the housing 17. This can limit the position of the second locking member 20. The effect of limiting the position of the first locking member 19 and the position of the second locking member 20 is better.

In one embodiment, the power conversion lock 16 also includes a microswitch 38. The second locking member 20 is provided with a projection 40 on the side facing away from the first locking member 19.
