Description

(ガイド機構15の構成)
本形態において、3本の連結軸12は各々、可動カバー20を開方向L1および閉方向L2に移動させる際にガイドするガイド機構15のガイド軸として利用されている。すなわち、3本の連結軸12の1本の連結軸12によって、第1ガイド軸121が構成されており、他の1本の連結軸12によって第2ガイド軸122が構成され、残りの連結軸12によって第3ガイド軸123が構成されている。一方、可動カバー20の筒状胴部22の外周面には、半円形状の突出部23が3個所に形成されており、3個所の突出部23の各々に、第1ガイド軸121が嵌った第1ガイド穴231、第2ガイド軸122が嵌った第2ガイド穴232、および第3ガイド軸123が嵌った第3ガイド穴233が形成されている。本形態において、3本の連結軸12は、軸線Lの周りに等角度間隔に形成されており、従って、3本のガイド軸(第1ガイド軸121、第2ガイド軸122、および第3ガイド軸123)、および3つのガイド穴(第1ガイド穴231、第2ガイド穴232、および第3ガイド穴233)も、軸線Lの周りに等角度間隔に形成されている。
(Configuration of guide mechanism 15)
In the present embodiment, each of the three connecting shafts 12 is used as a guide shaft of the guide mechanism 15 that guides the movable cover 20 when moving the movable cover 20 in the opening direction L1 and the closing direction L2. That is, one connecting shaft 12 of the three connecting shafts 12 constitutes the first guide shaft 121, the other connecting shaft 12 constitutes the second guide shaft 122, and the remaining connecting shafts 12 are constituted. The third guide shaft 123 is constituted by 12. On the other hand, on the outer peripheral surface of the tubular body portion 22 of the movable cover 20, semicircular protrusions 23 are formed at three locations, and the first guide shaft 121 is fitted in each of the three protrusions 23. A first guide hole 231, a second guide hole 232 in which the second guide shaft 122 is fitted, and a third guide hole 233 in which the third guide shaft 123 is fitted are formed. In this embodiment, the three connecting shafts 12 are formed at equal angular intervals around the axis L, and therefore, the three guide shafts (the first guide shaft 121, the second guide shaft 122, and the third guide shaft). The shaft 123 ) and the three guide holes (first guide hole 231, second guide hole 232, and third guide hole 233) are also formed around the axis L at equal angular intervals.

また、可動カバー20が開方向L1に移動する際、可動カバー20が時計周りCWに回転しようとするが、その際の回転は、第1ガイド軸121に対して第1ガイド穴231の内面の水平方向Hの一方側Haの部分231aが当接することによって阻止され、この状態で、第1ガイド軸121と第1ガイド穴231の内面の水平方向Hの一方側Haの部分231aとが摺動する。これに対して、可動カバー20が閉方向L2に移動する際、可動カバー20が反時計周りCCWに回転しようとするが、その際の回転は、第1ガイド軸121に対して第1ガイド穴231の内面の水平方向Hの他方側Hbの部分231bが当接することによって阻止され、この状態で、第1ガイド軸121と第1ガイド穴231の内面の水平方向Hの他方側Hbの部分231bとが摺動する。このような場合でも、第1ガイド穴231が長円形であるため、ガタつきが発生しないとともに、クリアランスが少なすぎて可動カバー20が動きにくくなるという事態が発生しにくい。 Further, when the movable cover 20 is moved in the opening direction L1, the movable cover 20 attempts to rotate in the clockwise CW, the rotation at that time, the first guide shaft 121 of the inner surface of the first guide hole 231 The part 231a on the one side Ha in the horizontal direction H is blocked by contact, and in this state, the first guide shaft 121 and the part 231a on the one side Ha in the horizontal direction H on the inner surface of the first guide hole 231 slide. To do. In contrast, when the movable cover 20 is moved in the closing direction L2, the movable cover 20 attempts to rotate in the counterclockwise CCW, rotation in that case, the first guide hole with respect to the first guide shaft 121 A portion 231b on the other side Hb in the horizontal direction H of the inner surface of 231 is blocked by abutting, and in this state, a portion 231b on the other side Hb in the horizontal direction H of the inner surface of the first guide shaft 121 and the first guide hole 231. And slide. Even in such a case, since the first guide hole 231 has an oval shape, rattling does not occur, and the situation in which the movable cover 20 becomes difficult to move due to too little clearance is unlikely to occur.

また、回転体配置穴25に切り欠き28を設けると、ダンパ装置1を組み立てる際、回転体31の係合部36が切り欠き28に嵌るおそれがあるが、本形態では、切り欠き28に凸部29が形成されている。このため、ダンパ装置1を組み立てる際、回転体31の係合部36が切り欠き28に嵌ってしまうという事態を回避することができる。
Further, if the cutout 28 is provided in the rotary body placement hole 25, the engaging portion 36 of the rotary body 31 may be fitted into the cutout 28 when the damper device 1 is assembled, but in the present embodiment, the cutout 28 is convex. The part 29 is formed. Therefore, when the damper device 1 is assembled, it is possible to avoid a situation in which the engaging portion 36 of the rotating body 31 fits into the notch 28.
