1. A saddle raising device comprising:
a fixed tube configured to be inserted into a frame of a bicycle;
a rising rod having an upper end portion to which a saddle of the bicycle is to be mounted, the rising rod being slidably inserted in the fixed tube;
a stroke spring biasing the rising rod upwardly in an axial direction of the fixed tube, relative to the fixed tube;
a locking mechanism configured to lock the rising rod relative to the fixed tube at a predetermined height; and
a locking/unlocking switch configured to switch the locking mechanism between an ascent/descent allowing state, in which the locking mechanism allows ascent and descent of the rising rod, and a locking state, in which the locking mechanism restricts the ascent and descent of the rising rod;
wherein the locking mechanism includes:
an engaging member in the fixed tube and having a plurality of engaging recesses arranged in the axial direction of the fixed tube; and
a claw member carried by the rising rod and having a claw configured to be capable of meshing with any one of the engaging recesses;

wherein the locking/unlocking switch includes:
a wire configured to receive a pulling force inputted from an operating portion of the bicycle when a rider of the bicycle operates the operating portion; and
a claw state switching member configured to be pulled by the wire while the pulling force is being applied to the wire, and thereby disengage the claw; from the engaging recess, and with the pulling force removed from the wire, configured to press the claw into meshing engagement with a selected one of the engaging recesses.
