We report measurement of trigonometric parallax of IRAS 05168+3634 with VERA .
The parallax is 0.532 \pm 0.053 mas , corresponding to a distance of 1.88 ^ { +0.21 } _ { -0.17 } kpc .
This result is significantly smaller than the previous distance estimate of 6 kpc based on kinematic distance .
This drastic change in the source distance revises not only physical parameters of IRAS 05168+3634 , but also its location of the source , placing it in the Perseus arm rather than the Outer arm .
We also measure proper motions of the source .
A combination of the distance and the proper motions with systemic velocity yields rotation velocity ( \Theta ) of 227 ^ { +9 } _ { -11 } km s ^ { -1 } at the source , assuming \Theta _ { 0 } = 240 km s ^ { -1 } .
Our result combined with previous VLBI results for six sources in the Perseus arm indicates that the sources rotate systematically slower than the Galactic rotation velocity at the LSR .
In fact , we show observed disk peculiar motions averaged over the seven sources in the Perseus arm as ( U _ { mean } , V _ { mean } ) = ( 11 \pm 3 , - 17 \pm 3 ) km s ^ { -1 } , indicating that these seven sources are systematically moving toward the Galactic center , and lag behind the Galactic rotation .
