1. A shift lever that receives a manipulation force to change a range of an automatic transmission in a vehicle, the shift lever comprising:
a lever main body; and
a shift knob located at a distal end of the main body, wherein
the lever main body has a lever shaft and a push rod located in the lever shaft to be urged toward the distal end,
the shift knob has a button for unlocking that receives a pushing manipulation force in a direction intersecting the push rod, a holder fixed to the lever shaft for holding the button, and a converter held by the holder slidably in an axial direction of the push rod by contact with a distal end of the push rod for converting a momentum in a pushing manipulation direction of the button into a momentum force in the axial direction to shift the push rod, and
the converter has a pushed surface to be pushed by the button in response to the pushing manipulation, the pushed surface being configured to be pushed by the button when the button moves from a home position to a stroke end to move the converter in the axial direction,
the pushed surface occupying only a region of the converter that is away from a central axis of the push rod in a releasing direction that is opposite to a pushing direction.
