<p><P>PROBLEM TO BE SOLVED: To provide an angle drive unit having a structure capable of improving durability in view of a lateral hole part of an angle drive. <P>SOLUTION: An angle drive 1 includes: a square shaft-like angle drive part 2 having one end to which an attachment transmitting torque to a fastening member is detachably attached; a torque transmission part 3 integrally formed at the other end of the angle drive part 2 and transmitting input torque to the angle drive part 2; a bottomed lateral hole part 4 formed at one side surface at the one end side of the angle drive part 2 and in a direction perpendicular to the axial direction of the angle drive part 2; a spring member 5 disposed at the lateral hole part 4; and an engagement member 6 biased by the spring member 5 to protrude outward from an opening of the lateral hole part 4 and detachably engaged with the attachment. The angle drive part 2 includes an engagement part 11 engaged with the attachment at the one end side and a non-engagement part 12 not engaged with the attachment at a more distal end side than the engagement part 11, and the lateral hole part 4 is formed at a formation region of the non-engagement part 12. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
