An insertion port 413O of the locking hole 413 is open to the extension portion 42. As shown in FIG.
Therefore, compared to the case where the locking hole 413 is formed only in the support component main body 41, the engagement from the insertion opening 413O of the locking hole 413 to the first insertion hole 412 (base end side insertion hole 412) is reduced. A longer length of the base end portion 413B of the stop hole 413 can be ensured. This improves the straightness of the fixture 5 inserted into the locking hole 413 . It is possible to easily insert the distal end portion of the fixing tool 5 protruding into the area of ( ) into the distal end portion 413 T of the locking hole 413 .

Further, in the carrying handle 2 of the present embodiment, the distal end portion 413T and the proximal end portion 413B of the locking hole 413 separated by the notch recess 414 are connected by the connecting cylinder 44 . Therefore, the fixture 5 can be passed through the inside of the connecting tube 44 from the proximal end portion 413B of the locking hole 413 to the distal end portion 413T of the locking hole 413 . As a result, the fixture 5 can be easily passed through the distal end portion 413T and the proximal end portion 413B of the locking hole 413 separated by the notch recess 414 . This effect is particularly useful when the length of the base end portion 413B of the locking hole 413 formed in the extension portion 42 is short, or when the extension portion 42 is not provided.

In addition, in the carrying handle 2 of the present embodiment, the second end portion 41B of the handle support component 4 located on the front side in the direction of insertion of the insertion portions 32 and 33 into the insertion holes 411 and 412 (on the side opposite to the first end portion 41A) , a fixing hole 415 for fixing to the lower surface 1b of the projector body 1 is formed. As a result, even if the handle main body 3 (gripping portion 31) of the carrying handle 2 provided on the lower surface 1b of the projector main body 1 is grasped and lifted upward, the handle support component 4 separates (separates) from the lower surface 1b of the projector main body 1. ) can be effectively suppressed. This point will be described below.
