As shown in FIG. 4, the left and right side portions 82 of the filter member 8 are disposed on both the left and right sides of the water passage member 5. Each side surface portion 82 is formed in a semicircular shape that matches the inner surface of the eaves 2 as viewed from the left-right direction.

フィルター部材８の各側面部８２は、軒樋２の底部２３上に載置されている。各側面部８２の円弧状の下面は、軒樋２の内面の周方向の全体に亘って接触している。これによりフィルター部材８の前後方向及び下方への移動が規制されている。また、フィルター部材８の各側面部８２は、左右方向から見たときに、軒樋２の内側に形成される空間の全体（雨水が流れる領域）に亘って配置され、通水部材５の左右両側を覆っている。 Each side surface portion 82 of the filter member 8 is placed on the bottom portion 23 of the eaves 2. The arc-shaped lower surface of each side surface 82 is in contact with the entire inner surface of the eaves 2 in the circumferential direction. This restricts the movement of the filter member 8 in the front-rear direction and in the downward direction. Further, each side portion 82 of the filter member 8 is disposed over the entire space (region where rainwater flows) formed inside the eaves bowl 2 when viewed from the left-right direction, and Covers both sides.

図６に示されるように、フィルター部材８の上面部の中央部には、上下に貫通する嵌込孔８３０が形成されている。嵌込孔８３０は平面視円形の孔であって、その直径はねじ部材６の外径よりも僅かに大きい。 As shown in FIG. 6, a fitting hole 830 penetrating vertically is formed at the center of the upper surface of the filter member 8. The fitting hole 830 is a circular hole in plan view, and its diameter is slightly larger than the outer diameter of the screw member 6.

図５に示されるように、フィルター部材８の嵌込孔８３０には、突出部材４に螺合されたねじ部材６が嵌め込まれている。これによりフィルター部材８の通水部材５に対する水平方向の移動が規制されている。 As shown in FIG. 5, the screw member 6 screwed into the protruding member 4 is fitted into the fitting hole 830 of the filter member 8. Thereby, the horizontal movement of the filter member 8 with respect to the water passage member 5 is restricted.

すなわち、フィルター部材８は、両側の側面部８２を軒樋２の底部２３上に載置して軒樋２の内側に嵌め込み、嵌込孔８３０にねじ部材６を嵌め込むことで、軒樋２及びこれに取り付けられた通水部材５の両者に対して固定されている。 That is, the filter member 8 is configured such that the side portions 82 on both sides are placed on the bottom 23 of the eaves 2 and fitted inside the eaves 2, and the screw member 6 is fitted into the fitting hole 830, thereby And it fixes with respect to both of the water flow members 5 attached to this.

フィルター部材８と軒樋２により、軒樋２の落とし口２００の上方空間１１が囲まれており、この空間１１には通水部材５が配置されている。 The filter member 8 and the eaves 2 surround the upper space 11 of the pit 200 of the eaves 2, and the water flow member 5 is disposed in the space 11.

軒樋２及び通水部材５に対して固定されたフィルター部材８は、フィルター部材８を上方に持ち上げて、ねじ部材６を嵌込孔８３０から外し且つ両側の側面部８２を軒樋２から外すことで、簡単に取り外すことができる。 The filter member 8 fixed to the eaves bowl 2 and the water passage member 5 lifts the filter member 8 upward to remove the screw member 6 from the fitting hole 830 and remove the side portions 82 on both sides from the eave bowl 2. It can be easily removed.

図４に示されるようにドレン１が軒樋２に取り付けられた状態では、軒樋２を流れる雨水は、フィルター部材８の側面部８２の通水孔８４を通過する。この雨水は、通水部材５の両連結部５７，５８の間、及び下側の挿通孔５６０を順に通り、軒樋２の落とし口２００から排水筒３に排出される。ここで、軒樋２を流れる雨水がフィルター部材８の通水孔８４を通過するときには、フィルター部材８の網状の側面部８２によって雨水に含まれる落ち葉等のごみが捕集される。 As shown in FIG. 4, in a state where the drain 1 is attached to the eave cage 2, rainwater flowing through the eave cage 2 passes through the water passage holes 84 of the side surface portion 82 of the filter member 8. The rainwater passes through the connecting portions 57 and 58 of the water passage member 5 and the lower insertion hole 560 in order, and is discharged from the outlet 200 of the eaves 2 to the drain tube 3. Here, when rainwater flowing through the eaves 2 passes through the water passage hole 84 of the filter member 8, dust such as fallen leaves contained in the rainwater is collected by the net-like side surface portion 82 of the filter member 8.

本実施形態の軒樋２の排水構造にあっても、排水筒３とこれに固定された通水部材５とで軒樋２の底部２０を挟み込み、排水筒３及び通水部材５を軒樋２に取り付けた状態のまま、フィルター部材８を通水部材５から取り外すことができる。従って、フィルター部材８で捕集したごみを取り除く作業を、排水筒３及び通水部材５を軒樋２に取り付けた状態のまま、フィルター部材８を取り外して、簡単に行うことができる。 Even in the drainage structure of the eaves bowl 2 according to the present embodiment, the bottom 20 of the eaves bowl 2 is sandwiched between the drainage cylinder 3 and the water passage member 5 fixed to the drainage cylinder 3, and the drainage cylinder 3 and the water passage member 5 are attached to the eaves bowl. The filter member 8 can be removed from the water member 5 while being attached to the water member 2. Therefore, the operation of removing the dust collected by the filter member 8 can be easily performed by removing the filter member 8 while the drain tube 3 and the water passage member 5 are attached to the eaves 2.

なお、第１実施形態及び第２実施形態では、排水筒３の軸方向が軒樋２の底部２０と垂直な方向に対して傾斜しているが、平行であってもよい。また、第１実施形態及び第２実施形態において、排水筒３に連結される下流側の管材は、呼び樋に限られず、エルボー等の継手や竪樋であってもよい。また、第１実施形態及び第２実施形態における通水部材５は、ねじ部材６と一体に形成されてもよい。また、この他、第１実施形態及び第２実施形態における軒樋２の排水構造は、本発明の趣旨を逸脱しない範囲で設計変更可能である。 In addition, in 1st Embodiment and 2nd Embodiment, although the axial direction of the drain tube 3 inclines with respect to the direction perpendicular | vertical to the bottom part 20 of the eaves bowl 2, it may be parallel. Moreover, in 1st Embodiment and 2nd Embodiment, the downstream pipe connected with the drain tube 3 is not restricted to a call, and may be a joint or a rod such as an elbow. Further, the water passing member 5 in the first embodiment and the second embodiment may be formed integrally with the screw member 6.
