An accelerator position sensor unit capable of not only easily performing positioning of the accelerator position sensor unit with respect to a handlebar but also stably fixing the accelerator position sensor unit to the handlebar with a simple configuration. An accelerator position sensor unit 1 includes an accelerator position sensor main body 3 that detects a rotation angle of a throttle pipe 12 supported by a cylindrical handlebar 11 in a state of being rotatable around a central axis O11 of the handlebar 11 along an outer circumference surface 111 of the handlebar 11, and a sensor case 4 that houses the accelerator position sensor main body 3. The sensor case 4 includes an extending portion 53 extending along a direction of the central axis O11. The extending portion 53 is sandwiched between the handlebar 11 and a cover 7 that covers the accelerator position sensor unit 1.
