There is also a problem in terms of durability, such as the shutter becoming defective due to loosening.

特許文献2のシリンダー錠では、(d) 2個のスライド部材は、内筒の凹部と、内筒の前面に設けたカバーとの間に遊嵌され、内筒に直接に装着されていない。そのため、2個のスライド部材を付勢するバネの配設状態や使用頻度等や、合鍵による施解錠操作時の外力の掛り具合等によっては、前記2個のスライド部材が揺動して、合鍵が内筒の鍵穴に円滑に抜き差しし難い上に、合鍵と内筒とが一体に回動され難く、無理に合鍵に回転トルクを掛けると該合鍵が使用不可能となるという問題があった。   In the cylinder lock of Patent Document 2, (d) the two slide members are loosely fitted between the concave portion of the inner cylinder and a cover provided on the front surface of the inner cylinder, and are not directly attached to the inner cylinder. Therefore, depending on the arrangement state and frequency of use of the springs for urging the two slide members, and the degree of external force applied during the locking / unlocking operation using the key combination, the two slide members may swing, However, it is difficult to smoothly insert and remove the key into the key hole of the inner cylinder, and it is difficult for the key and the inner cylinder to rotate together, and it becomes impossible to use the key when the torque is forcibly applied to the key.

(e) また、内筒の前端部にシリンダーカバーを固定すると共に、シリンダーカバーと内筒の前面との間にカバーを固定するために、部品点数も多く構造が複雑で、組付け作業も面倒であった。   (E) Since the cylinder cover is fixed to the front end of the inner cylinder and the cover is fixed between the cylinder cover and the front surface of the inner cylinder, the number of parts is large and the structure is complicated, and the assembly work is troublesome. Met.

(f) 更に、前記シリンダーカバー、スライド部材の前面に固定したカバー、それらを固定するための構成部材や加工を必要とし、全体として高価となる難点があった。   (F) Further, the cylinder cover, the cover fixed to the front surface of the slide member, the constituent members and processing for fixing them are required, and there is a problem that the whole is expensive.

The durability of the entire lock can be improved.
Furthermore, a key guide cover and a cover plate as shown in Patent Document 1 are unnecessary, and a cylinder cover and a cover as shown in Patent Document 2 are also unnecessary, and a complicated structure for fixing them is also unnecessary. A troublesome assembling work is not required, and the number of components is small, so that an inexpensive cylinder lock can be provided.

請求項2のシリンダー錠によれば、請求項1の効果のほかに、蓋体である一対の分割部材の両方が開閉する両開き式の構成を有するものであるから、左右が対称の一対の分割部材を構成すればよいため、金型製作上も便利で、付勢部材であるバネも同一のものを採用できる利点がある。   According to the cylinder lock of the second aspect, in addition to the effect of the first aspect, since it has a double-open structure in which both of the pair of divided members that are lids are opened and closed, a pair of divided left and right are symmetrical. Since the members only need to be configured, there is an advantage that the mold can be manufactured conveniently, and the same spring can be adopted as the biasing member.

請求項3のシリンダー錠によれば、請求項1の効果のほかに、蓋体である一対の分割部材の一方のみが可動構造で、他方は固定構造であって、一方の分割部材のみが開閉する片開き式の構成を有するものであるから、前記請求項2に記載の両開き式に比べて、構造が簡単であると共に、付勢手段(バネ)は1個のみでよいので部品代が節減でき、さらに、一方の分割部材だけを付勢手段(バネ)で付勢するものであるため、該分割部材の開閉の動きが円滑である。   According to the cylinder lock of the third aspect, in addition to the effect of the first aspect, only one of the pair of divided members as the lid body is a movable structure and the other is a fixed structure, and only one of the divided members is opened and closed. Compared with the double-open type according to claim 2, the structure is simple, and only one urging means (spring) is required, so that the part cost is reduced. In addition, since only one of the divided members is urged by the urging means (spring), the movement of opening and closing the divided member is smooth.
