Provided is a seat slide adjuster suitable for weight saving. The seat slide adjuster has a structure in which two rows of opening parts (151b, 151b) as parts to be engaged are formed in a locking plate (151), which constitutes a locking mechanism (15), at a predetermined distance from each other in an orthogonal direction to the longitudinal direction of the locking plate, and when in a locked state, the opening parts engage with locking tooth parts (11e, 11e) disposed on both sides of a lower rail (11). Because the force generated between the locking plate (151) and lower rail (11) acts on locking tooth parts (11e, 11e) on both sides in a well-balanced manner without being biased to either side, durability of these constituent members can be improved. In addition, because the two rows of opening parts (151b, 151b) of the locking plate (151) are used for the engagement, looseness of the locking plate (151) is less likely to occur.
