out of the lock beak portions, the lock beak portion disposed in the front end side has a relatively small amount of projection, and the lock beak portion disposed in the base end side has a relatively large amount of projection.
4. The lock mechanism according to claim 3 , wherein
the flange portion includes a portion defining a through-hole through which the arm portion penetrates along the axial direction, and
in a state where the lock beak portion is locked to the mounting panel, the arm portion penetrates through a mounting hole formed in the mounting panel and the through-hole along the axial direction, has the base end disposed in a side of the axial direction with respect to the mounting panel, and has the front end disposed in another side of the axial direction with respect to the mounting panel.
5. The lock mechanism according to claim 1 , wherein
out of the lock beak portions, the lock beak portion disposed in the front end side has a relatively small amount of projection, and the lock beak portion disposed in the base end side has a relatively large amount of projection.
6. The lock mechanism according to claim 2 , wherein
the flange portion includes a portion defining a through-hole through which the arm portion penetrates along the axial direction, and
in a state where the lock beak portion is locked to the mounting panel, the arm portion penetrates through a mounting hole formed in the mounting panel and the through-hole along the axial direction, has the base end disposed in a side of the axial direction with respect to the mounting panel, and has the front end disposed in another side of the axial direction with respect to the mounting panel.
7. The lock mechanism according to claim 5 , wherein
the flange portion includes a portion defining a through-hole through which the arm portion penetrates along the axial direction, and
in a state where the lock beak portion is locked to the mounting panel, the arm portion penetrates through a mounting hole formed in the mounting panel and the through-hole along the axial direction, has the base end disposed in a side of the axial direction with respect to the mounting panel, and has the front end disposed in another side of the axial direction with respect to the mounting panel.
8. The lock mechanism according to claim 1 , wherein
the flange portion includes a portion defining a through-hole through which the arm portion penetrates along the axial direction, and
in a state where the lock beak portion is locked to the mounting panel, the arm portion penetrates through a mounting hole formed in the mounting panel and the through-hole along the axial direction, has the base end disposed in a side of the axial direction with respect to the mounting panel, and has the front end disposed in another side of the axial direction with respect to the mounting panel.
9. A connector comprising:
a connector housing that is provided with a terminal along an axial direction and is matable with a counterpart connector; and
a lock mechanism that is capable of locking the connector housing to a mounting panel, wherein
the lock mechanism includes:
a flange portion that is formed in a manner projecting from the connector housing in an intersection direction intersecting with the axial direction;
an arm portion that is supported by the connector housing at a base end, is extended from the connector housing to the flange portion side along the axial direction, has a free front end, and is bendable along the intersection direction; and
a lock beak portion that projects from the arm portion to a side opposite to the connector housing side along the intersection direction, and is lockable to the mounting panel disposed between the lock beak portion and the flange portion in the axial direction, and
the lock beak portion includes a plurality of lock beak portions provided along the axial direction at a certain interval.
10. A wire harness comprising:
a conductive wiring member; and
a connector that is connected with the wiring member, wherein
the connector includes:
a connector housing that is provided with a terminal connected with the wiring member along an axial direction and is matable with a counterpart connector; and
a lock mechanism that is capable of locking the connector housing to a mounting panel,
the lock mechanism includes:
a flange portion that is formed in a manner projecting from the connector housing in an intersection direction intersecting with the axial direction;
an arm portion that is supported by the connector housing at a base end, is extended from the connector housing to the flange portion side along the axial direction, has a free front end, and is bendable along the intersection direction; and
a lock beak portion that projects from the arm portion to a side opposite to the connector housing side along the intersection direction, and is lockable to the mounting panel disposed between the lock beak portion and the flange portion in the axial direction, and
the lock beak portion includes a plurality of lock beak portions provided along the axial direction at a certain interval.
