Lever fitting-type connector

A lever fitting-type connector of a power circuit cutoff device performing supplying of and cutting off of power from a power supply with the lever fitting-type connector fitted in and separated from a vehicle connector disposed on a vehicle side, the lever fitting-type connector comprising:

• a plug housing that has a pair of guide pins provided to project outward from outer wall surfaces of facing sidewalls, respectively;
• a lever that has guide grooves, into which the guide pins are inserted, in facing sidewalls, and that straddles the plug housing so as to be pivotably and slidably supported with respect to the plug housing;
• a contact member that is formed in one wall surface of an inner wall surface of a sidewall of the lever with the guide groove formed, and an outer wall surface of the plug housing with the guide pin formed;
• and
• a triangular recess with which the contact member comes into contact during sliding of the lever, and which is formed in a region from a sliding start position of the lever to a sliding end position of the lever, in the inner wall surface of the lever or the outer wall surface of the plug housing, in which the contact member is not formed,
• wherein the triangular recess includes a first inclined surface that extends in a direction from the sliding start position toward the sliding end position of the lever and that is inclined in a projecting direction of the contact member, and a second inclined surface that extends in a direction from an edge of the first inclined surface on the sliding end position side toward the sliding end position and that is inclined in a direction opposite to the projecting direction of the contact member, and
• wherein, with a sliding direction of the lever as a reference, an inclined angle of the second inclined surface is smaller than an inclined angle of the first inclined surface.
