To facilitate the positioning of axis center positions of a first bearing and a second bearing at a regular position in the direction orthogonal to a rotation axis direction and a regular position in a rotation axis direction on a support base surface.SOLUTION: A hoisting machine 1 includes a first center boss 17 positioning an axis center position of a first bearing base 6 at a first predetermined position in a surface direction on a base surface of a support base 8. A hole to be positioned of the first bearing base 6, through which the first center boss 17 passes, allows the rotation of the first bearing base 6 around a first virtual shaft line A1. The hoisting machine 1 further includes a second center boss 19 positioning an axis center position of a second bearing base 7 at a second predetermined position in the surface direction on the base surface of the support base 8. A hole to be positioned of the second bearing base 7, through which the second center boss 19 passes, allows the rotation of the second bearing base 7 around a second virtual shaft line A2. A first bearing base fixing bolt 13 locks the rotation of the first bearing base 6. A second bearing base fixing bolt 16 locks the rotation of the second bearing base 7.SELECTED DRAWING: Figure 1

    【課題】支持台面上において、第1軸受け及び第2軸受けのそれぞれにおける軸中心位置を、回転軸線方向と直交する方向の正規位置と回転軸線方向の正規位置とに容易に位置決めする。【解決手段】巻上機1は、第1軸受台6の軸中心位置を、支持台8の台面における面方向の第1所定位置に位置決めする第1センターボス17を備える。第1センターボス17を貫通させる第1軸受台6の被位置決め穴は、仮想第1軸線A1を中心とする第1軸受台6の回転を許容する。また、巻上機1は、第2軸受台7の軸中心位置を、支持台8の台面における面方向の第2所定位置に位置決めする第2センターボス19を備える。第2センターボス19を貫通させる第2軸受台7の被位置決め穴は、仮想第2軸線A2を中心とする第2軸受台7の回転を許容する。第1軸受台固定ボルト13は、第1軸受台6の回転を係止し、第2軸受台固定ボルト16は、第2軸受台7の回転を係止する。【選択図】図1
