Abstract: A terminal fitting including a cylindrical portion into which a mating terminal is to be inserted; and a contact beam provided inside the cylindrical portion, the contact beam extending toward an insertion direction of the mating terminal into the cylindrical portion, being elastically deformable along a deflection direction of the contact beam and including a protruding portion extending in a direction intersecting the deflection direction, and the cylindrical portion including a peripheral wall and an engagement portion to be engaged with the protruding portion to regulate a movement of the contact beam, the engagement portion including a first portion and a second portion protruding from the peripheral wall of the cylindrical portion toward an inside of the cylindrical portion to regulate the movement of the contact beam in the deflection direction and in the insertion direction respectively.

Abstract: The connector includes: a housing provided with a terminal accommodating chamber; a terminal to be accommodated in the terminal accommodating chamber; a locking lance flexibly provided in the terminal accommodating chamber, a free end side of the locking lance configured to abut on the terminal when the terminal is inserted into the terminal accommodating chamber, thereby the locking lance being restored after being bent, thereby the free end side being capable of locking the terminal in the terminal accommodating chamber; and a thin-walled portion flexibly provided on the free end side of the locking lance, a thickness in a bending direction of the locking lance being set to be smaller than a thickness on a base end side of the locking lance in the thin-walled portion.
