されるものではなく、種々の機構を採用し得る。To adjust the lateral position of the elbow cover 6, the operation button 17 is depressed with a finger to release the engagement between the engaging claw 19 and the engaging concave portion 16, and in this state, the elasticity is reduced. The finger may be released from the operation button 17 after the elbow cover 6 is slid and adjusted against the elastic force of the urging means (tensile coil spring 12) or with the elastic force. Then
The engaging claw 19 of the latch rod 18 is engaged with the engaging recess 1 of the guide rail 8.
