A temporary fixation boss includes: a shaft portion; a flared portion; and claw portions. The shaft portion has a diameter smaller than a diameter of an insertion hole. The flared portion is provided at one end of the shaft portion in a manner to be flared in multi steps from an outer periphery of the shaft portion throughout the whole circumference of the shaft portion. The claw portions are so formed that a distance from the shaft center of the shaft portion to a tip end of the claw portions in a radial direction of the shaft portion is larger than a distance from the shaft center to a tip end of the flared portion, and smaller than a distance from the shaft center to the inner edges of the insertion hole when the shaft center is aligned with the center axis of the insertion hole.

Temporary fixation boss and electrical junction box

An electric junction box is provided having a receiving portion enabling a joint to be securely press-fitted into a joint, even if the outer diameter of the joint varies within a wide range. An electric junction box is comprised of a joint having electrical conduits that are electrically connected to each other at their terminals, and a cap disposed on the terminals, and a receiving portion which the joint is press-fitted into. The receiving portion comprises a recess having an inner surface facing an outer surface of the joint, and a rib projection disposed on the inner surface of the recess. The rib projection has a tapered portion inclined toward the bottom of the recess thus approximating the center portion of the bottom.
