Therefore, according to this modification, the module 363 can be smoothly housed in the housing 343.
  • the module 363 when the module 363 is provided with a plurality of dovetail tenons 26, the module 363 may be provided with a plurality of protrusions 42 corresponding to each of the plurality of dovetail tenons 26. However, the protrusion 42 corresponding to at least one of the plurality of dovetail tenons 26 may be omitted.
  • the engagement structure 18 of the embodiment may be applied to members other than the terminal block 12.
  • the housing member (34) having the opening (38) is inserted into the opening (38) along the insertion direction to connect the housing member (36) housed in the housing member (34).
  • the engagement structure 18 may be applied to other than the terminal block 12 within the range of matching.
  • a first invention engages a housing member (34) having an opening (38) with a housing member (36) that is housed in the housing member by being inserted into the opening along the insertion direction.
  • the engagement structure (18) includes a latch structure (24) and a dovetail structure (22), and the latch structure extends from the opening end (38a) of the opening in the housing member along the insertion direction.
  • a dovetail tenon formed in the housing member from the open end along the insertion direction, and allowing the dovetail tenon to move to a predetermined position along the insertion direction; a dovetail hole (28) that engages with the dovetail hole (28), and the dovetail tenon has a dovetail hole (28) that engages with the dovetail hole (28) before the protrusion and the open end come into contact when the accommodated member is inserted into the accommodation member. It is an engagement structure that engages with a hole.
  • the tip (26a) of the dovetail tenon in the insertion direction may be located closer to the insertion direction than the tip (30a) of the protrusion in the insertion direction. As a result, the engagement on the dovetail structure side is started before the engagement on the latch structure side.
  • the protrusion is inclined such that the thickness in the protrusion direction of the protrusion becomes smaller in the insertion direction, and the tip (26a) of the dovetail tenon in the insertion direction is closer to the protrusion in the insertion direction.
  • the protrusion may be located at the same position as the tip (30a) in the insertion direction, or on the opposite side from the tip of the protrusion.
  • the protrusion and the dovetail tenon may be connected. This reduces the possibility that the accommodated member will fall off from the accommodation member.
  • Two of the protrusions may be provided so as to sandwich the dovetail tenon. This reduces the possibility that the accommodated member will fall off from the accommodation member.
