It is lower than the position P3 of one end on the side far from the holding part 120 among both ends in the length direction D3. Thereby, in a state where the sensor unit 300 is attached to the holding unit 120, the cover unit 130 can be disposed at a position that does not interfere with the detection range R <b> 1 of the sensor 311. In addition, the sensor 311 can be disposed inside the light distribution L1 that connects the LED 111 of the light source unit 110 and the boundary between the first curved portion 131 and the second curved portion 132 of the cover portion 130. Therefore, it is possible to obtain a desired detection range R1 of the sensor unit 300 while suppressing the influence on the light distribution of the light source unit 101 due to the presence of the sensor unit 300.

  Further, the end surface 411 of the first storage unit 410 is provided with an opening 413 that exposes at least a part of the knob 331 attached to the switch 314 to the outside.

  In addition, a step is provided on the end surface 411 of the first storage unit 410, an opening 412 that exposes at least a part of the sensor 311 to the outside in the high step 414, and at least a part of the knob 331 in the low step 415. An opening 413 is provided to be exposed. The opening 412 of the high step 414 is formed to have the same shape and size as the outer periphery of the lens portion of the sensor 311 protruding from the opening 412. For this reason, dust can be prevented from entering the inside of the housing 320 from the opening 412. The opening 413 of the lower step 415 is smaller than the flange 332 of the switch cover 330 in the sliding direction of the knob 331 protruding from the opening 413, sufficiently larger than the knob 331, and in a direction perpendicular to the sliding direction. It is formed so as to be smaller than the flange portion 332 and larger than the size of the knob 331. For this reason, it is possible to prevent dust from entering the housing 320 from the opening 413 while allowing the knob 331 to slide. When the lid 332 of the switch cover 330 is operated not only to prevent dust from entering but also to contact the inner surface of the lower step 415 so that the switch cover 330 fits securely to the switch 314. Further, the switch cover 330 is prevented from being displaced from the switch 314, and the operability is improved.

It extends to a position in front of the receiving portion 511 while being gently inclined. When the sensor unit 300 is attached to the holding part 120, the hooking claw part 170 is gradually inserted into the through hole 501 from the other end edge in the longitudinal direction of the through hole 501. At this time, the protruding piece 512 is pressed by the hooking claw portion 170 and elastically deformed. When the hooking claw 170 reaches the vicinity of one end edge in the longitudinal direction of the through hole 501 and is hooked on the receiving part 511, the protruding piece 512 is detached from the hooking claw 170 and returns to the state before elastic deformation. Thereby, the protruding piece 512 prevents the hooking claw portion 170 hooked by the receiving portion 511 from moving along the longitudinal direction of the through-hole 501 and naturally coming off. As described above, since the protruding piece 512 is gently inclined from the middle, when the sensor unit 300 is detached from the holding portion 120, the protruding piece 512 is pressed and elastically deformed by the hooking claw portion 170. Thus, the hooking claw 170 can be easily removed from the through hole 501.
