To provide a height adjustment type headrest capable of maintaining stability and intensity even when a height adjustment margin of a head reception part is made longer.SOLUTION: A height adjustment type headrest 1 comprises: a lower unit 10 which comprises a pair of right and left first stays 11 inserted elevatably into a seat back upper part and a stay coupling part 12 for coupling upper ends of the pair of right and left first stays 11; and an upper unit 20 which is attached elevatably to the lower unit 10, and elevates with a head reception part 1a of the headrest 1. In the headrest, a pair of right and left first guided parts αwhich are guided while being slid to a first guide part αon a peripheral face of the pair of right and left first stays 11 are provided on a lower skeleton 21 on the upper unit 20, a second guide part βis provided on the stay coupling part 12 on the lower unit 10, and a second guided part βwhich is guided while being slid to the second guide part β, is provided on a portion other than the lower skeleton 21 on the upper unit 20.SELECTED DRAWING: Figure 4
