<p>Provided is a lifter structure which does not require strict dimension control. The lifter structure is provided with a lifter (10) and a housing (60) for guiding the lifter (10). The housing (60) comprises a bore (61) into which the lifter (10) can be inserted so as to be able to move backwards and forwards. Between the inner circumferential surface of the bore (61) of the housing (60) and the outer circumferential surface of the lifter (10) are formed a neighbouring region (65), in which the distance between both circumferential surfaces is adjacent, and separated regions (66), in which the distance between both circumferential surfaces in the direction of movement on both sides of the lifter (10) sandwiching the neighbouring region (65) is further apart than the neighbouring region (65).</p>
