    • PROBLEM TO BE SOLVED: To provide a bearing plate which can prevent looseness of a bolt for securing an actuator in a housing, and to provide the actuator for a variable valve mechanism of an internal combustion engine using the same.SOLUTION: A phase position of an end part 38a of a reinforcement rib 38 is separated (0-30°) more than the separation from a phase position of a bolt fastening part 32 to a phase position of a corner part 34a in a circumference direction of a claw part 34. Since then, around the bolt fastening part 32 of the bearing plate 14 to up to the corner part 34a of the claw part 34 in the circumference direction, the rigidity reduces and the elastic deformation increases. Accordingly, the balance of elastic deformation and plastic deformation is improved, and spring elements and coupling elements are joined in well balance at the bearing plate 14. This causes, even if a planetary and differential screw type of rotation-linear motion conversion mechanism is operated repeatedly in a variable valve mechanism, the permanent set of a ring-like plate 30 around a bolt fastening part 32 can be prevented. Thereby, the bolt fastening strength does not become reduced and looseness of the bolt can be prevented.
    • 要解决的问题:提供一种能够防止用于将致动器固定在壳体中的螺栓松动的轴承板,并且提供使用其的内燃机的可变气门机构的致动器。解决方案: 加强肋38的端部38a比从螺栓紧固部32的相位位置到爪部34的圆周方向的角位置34a的相位位置分离(0-30°)。 从那时起,在轴承板14的螺栓紧固部32周围向爪部34的角部34a延伸,刚性降低,弹性变形增大。 因此,弹性变形和塑性变形的平衡得到改善,并且弹簧元件和联接元件在轴承板14处平衡地接合。这导致即使行星式和差速螺旋式旋转线性运动转换机构被操作 在可变气门机构中重复地,可以防止围绕螺栓紧固部件32的环形板30的永久变形。 因此,螺栓紧固强度不会降低,并且可以防止螺栓的松动。
