Disclosed is a sliding type mobile telephone terminal comprising (a) a
main housing with upper and lower surfaces, (b) a sliding housing with
upper and lower surfaces and first and second guide slots symmetrically
formed on the lower surface to have a designated shape, and accepting in
a range of a first sliding length a closing force from the main housing
and accepting in a range of a second sliding length being disposed above
the first sliding length an opening force from the main housing, thereby
being closed into and opened from the main housing in a longitudinal
direction so that the lower surface of the sliding housing is slid on the
upper surface of the main housing, and (c) a module accommodated in the
main housing and associated with the first and second guide slots so as
to provide the opening and closing forces to the sliding housing.
