To reduce a height dimension of a traction gear.SOLUTION: A traction gear has a configuration where a projection piece 57 of a lift plate 56 is arranged inside an opening OP composed between guide blocks 26, 28 while using the guide blocks 26, 28 composed as separate components as members to guide and support movement of an engaging pin 24 in a direction of an axis line CL and being arranged in a state separated from each other by a prescribed distance. Thus, movement of the engaging pin 24 in the direction of the axis line CL is not restricted by contact between the projection piece 57 and the guide blocks 26, 28, As a result, a length of the engaging pin 24 in the direction of the axis line CL can be shortened and a height dimension of a traction gear 20 can be reduced in comparison to a conventional structure.SELECTED DRAWING: Figure 31
【課題】牽引装置の高さ寸法の低減を図ること。【解決手段】係合ピン24の軸線CL方向の移動をガイドおよび支持する部材として、別部品として構成され、かつ、互いに所定距離離れた状態で配置されるガイドブロック26,28を用いると共に、当該ガイドブロック26,28間に構成される開口OP内に、リフトプレート56の突出片57を配置する構成とする。これにより、係合ピン24の軸線CL方向の移動が、突出片57とガイドブロック26,28との接触によって規制されることがない。この結果、係合ピン24の軸線CL方向の長さを短縮することができ、従来構造に比べて牽引装置20の高さ方向の寸法の低減を図ることができる。【選択図】図31
