A through hole 33 through which the hose 4 is inserted is provided. A wall 34 is formed at one end of the body 31 at a position retracted inward from the end. The wall 34 has a mounting hole 35 at the rotation center 36 of the drum 3. The connecting member 37 is inserted into the mounting hole 35.

As shown in FIG. 3, the connecting member 36 includes a disk portion 42 having locking portions 41, 41 connected to the wall portion 34 in a face-to-face manner in a face-to-face manner. A downstream connection portion 43 protruding to one side from the disk portion 42 and connected to the water sprinkling side hose 4 in a state of being fitted to the outside; a projection portion protruding to the other side from the disk portion 42; The water supply side hose 23 is fitted The downstream connection portion 43 is formed integrally with the upstream connection portion 44 that is connected in a state where the water supply side hose 4 is fixed. In addition, a locking groove 47 is formed on the peripheral surface of the upstream connection portion 44 to lock the claw portion 46 (see FIG. 2) of the attachment 24. A groove 48 is also formed on the distal end side of the locking groove 47, and an O-ring 4 for ensuring watertightness between the connection member 37 and the attachment 24 is formed in the groove 48. 9 (see FIG. 2). As shown in FIG. 4, the connection member 37 includes an upstream connection portion 44 and a downstream connection portion.

A communication hole 51 is provided to communicate with 4 3, and both connecting portions 4 3 and 4 4 are formed in a cylindrical shape that allows water from the water supply side hose 23 to flow to the watering side hose 4. . A coil spring 52 as a holding member for preventing the hose from being crushed at the time of bending the hose is fitted in the communication hole 51, and the coil spring 52 is attached to the end of the coil spring 52. An extended portion 53 is formed in which the linear member to be formed is extended linearly. The extending portion 53 is bent in a rectangular shape, and a folded portion 54 is formed which is folded toward the coil spring 52.

On the other hand, the inner peripheral surface 61 of the connecting member 37 has a locking wall 6 protruding toward the center.

2 is extended in the circumferential direction, and the inner diameter of the opening 6 3 surrounded by the locking wall 6 2

64 is set to be smaller than the outer diameter dimension 65 of the coil spring 52. The width 66 of the coil spring 52 from the extending portion 53 to the end 54 a of the folded portion 54 is set to be larger than the inner diameter 64 of the opening 63. Is set.

In the present embodiment according to the above configuration, the connection member 3 fixed to the drum 3

When attaching the sprinkling hose 4 to 7, the coil spring 52 is inserted into the communication hole 51 of the downstream connection part 43, and the end 54 of the folded part 54 of the coil spring 52 is inserted. Until it passes through the locking wall 62 projecting from the inner peripheral surface 61. At this time, the width dimension 66 from the extension 53 of the coil spring 52 to the end 54a of the folded part 54 is the inner diameter 64 of the opening 63 surrounded by the locking wall 62. Although it is set to be larger, it is allowed to pass through the locking wall 62 by being elastically deformed. Then, after passing through the locking wall 62, the elastically deformed folded portion 54 is deformed in the opening direction by the elastic force, and extends from the extending portion 53 to the end 5 of the folded portion 54.

Up to 4a, the width dimension 66 is restored so as to be larger than the inner diameter dimension 64 of the opening 63. As a result, the end 54a of the folded portion 54 is securely locked to the locking wall 62, so that the coil spring 52 is prevented from moving in the removal direction. The inner diameter 64 of the opening 63 surrounded by the locking wall 62 is the same as that of the coil spring.

The outer diameter dimension 52 of the coil spring 52 is set to be smaller than that of the coil spring 52, and the coil spring 52 is prevented from moving in the insertion direction when the coil spring 52 comes into contact with the locking wall 62.

Accordingly, it is possible to prevent the coil spring 52 inserted into the downstream connection portion 43 from coming off, and also prevent movement in the insertion direction. Thus, the amount of protrusion from the downstream connection portion 43 can be maintained at a predetermined length.

In this state, as shown in FIG. 2, the supply side hose 4 is externally fitted to the coil spring 52 and the downstream side connection portion 43 to the supply side hose 4 and fixed to the connection member 37. The supply hose 4 is wound around the drum 3 through a through hole 33 provided in the body 31 of the drum 3. At this time, the coil spring 52 is fitted in the supply side hose 4 to prevent the hose 4 from being crushed by bending, and the coil spring 52 is set to have a length dimension that reaches the through hole 33. As described above, the projecting amount of the coil spring 52 from the downstream connection portion 43 is maintained at a predetermined length, and the coil spring 52 is inserted into the insertion hole 3 as described above. It can be reliably placed at the site inserted in 3.

Therefore, the coil spring 52 moves in the insertion direction, and it is difficult to position the coil spring 52 with respect to the sprinkling side hose 4. Specifically, the coil spring 52 is connected to the downstream connection portion 4 3. The coil spring 52 can be surely arranged in the insertion hole 33 where the water sprinkling side hose 4 is easily bent as compared with the conventional case where the coil spring 52 moves to the back. Thereby, the crush prevention effect can be reliably obtained. Industrial applicability As described above, in the hose reel according to the first aspect of the present invention, the holding member inserted into the connection portion can be prevented from coming off, and also can be prevented from moving in the insertion direction. Thereby, the amount of protrusion from the connection portion can be maintained at a predetermined length:

Therefore, the holding member moves in the insertion direction, and the holding member can be arranged at a portion where the hose is easily bent, compared to the related art in which the positioning of the holding member with respect to the hose is difficult.

Further, in the hose reel according to claim 2, the folded portion elastically deformed when passing through the locking wall provided in the connection portion is deformed in the opening direction by the elastic force, so that the end of the folded portion is engaged. It can be securely locked to the stop wall. Thereby, even if an external force is applied to the holding member attached to the connection portion, it is possible to prevent the holding member from being unintentionally detached.
