らの断面図である。 FIG. 5 is a schematic view showing the positional relationship between the muffling cylinder and the valve 23, in which the outer periphery of the cylindrical valve 23 is inscribed in each side wall 18 of the triangular muffling cylinder 17. With such a configuration, the valve 23 is connected to the side wall 1 of the muffling tube 17.
Although it moves up and down along line 8, it does not swing left or right. Further, since a large space 35 is formed at the corner portion 20 between the valve 23 and the muffling cylinder 17, the air that has entered to replace the oil can be moved above the muffling cylinder 17. Note that FIG. 2 is a sectional view taken along line A-A'.
又、第６図に示すように給油口キヤツプを横転

消音筒１７外に確実に抜ける。 Further, when the oil filler cap is turned over as shown in FIG. 6, at least one of its flow portions 20a is always located at the lowest position, so that the oil inside the muffling cylinder 17 is reliably drained to the outside of the muffling cylinder 17.
上記実施例は三角筒であつたが多角筒型にして
も同様の効果が得られる。しかし消音筒１７と弁
２３との空間が最も大きいのは三角筒である。 Although the above embodiment uses a triangular tube, the same effect can be obtained by using a polygonal tube. However, the triangular cylinder has the largest space between the muffling cylinder 17 and the valve 23.
なお、小孔１９、油流通部２０ａの形状は他の
形状でもよい。 Note that the small hole 19 and the oil flow portion 20a may have other shapes.
