Abstract

A seat sliding apparatus, includes: a pair of right and left upper rails; a pair of lock plates mounted respectively to the pair of right and left upper rails in such a manner such that vicinities of base portions of the lock plates are pivoted via a shaft so that the lock plates are capable of swinging around the shaft; lock holes formed on a lower portion of a free end of the lock plates to engage with lock gear teeth formed on the pair of right and left lower rails; a lock spring biasing the lock plates to swing so that the lock holes are engaged with lock gear teeth, whereby a movement of the seat main body in a front-and-rear direction is prevented, and whereby the seat main body can be moved in the front-and-rear direction by releasing the engagement: and an operation lever mounted to the pair of lock plates so that the lock plates can be operated simultaneously by operating the operation lever. In the construction, the operation lever at an end of the opposite side to the belt anchor mounted side is provided with a phase angle absorption means.
