1. A lock mechanism for locking engagement between a first member including a barrel section formed in a cylindrical shape and formed with a hole extending through in a radial direction and a second member inserted into the barrel section from one end of the barrel section, comprising:
an engaged section formed on an outer surface of the second member; and
an engagement member having one end portion fixed to an edge of the hole and long in an axial direction of the barrel section, the engagement member including an operating section formed in another end portion and having a gap with respect to the second member in the radial direction, a fulcrum section formed continuously from the operating section in the axial direction of the barrel section and configured to contact the second member in a state in which the operating section is pressed inward in the radial direction, an engaging section formed continuously from the fulcrum section in the axial direction, formed in a convex shape protruding inward in the radial direction, and engaging with the engaged section in the axial direction, and a deformation section formed continuously from the engaging section in the axial direction and configured to be bent to move the engaging section outward in the radial direction when the operating section is pressed inward in the radial direction.
