To provide an inline roller skate which has a hung upper chassis and does not damage the stability of skater at the time of forward moving and performance as skating.

This inline roller skate is composed of an upper chassis 2 for fixing boots 1 and two lower chassises 4 at least for holding rollers 5, 6, 7 and 8. The upper chassis 2 is supported within the range of square A at the front end part onto the lower chassises 4. One side of the square A is 150mm, its lower edge is in contact with the ground, and the front roller 5 is included within that range. The vertical edge on the front side passes in front of the front roller. The upper chassis is elastically fitted onto the lower chassis.
