Alternatively, a key cylinder 14 that can be rotated by mounting a mechanical key 13 to be described later, a knob base portion 15 fixed to the key cylinder 14, and an operation knob 16 that can be attached to and detached from the knob base portion 15 are configured.

  This cylinder lock 11 is used when a predetermined signal is transmitted / received between the portable electronic key 12 and an in-vehicle control circuit (not shown), or when the mechanical key 13 or the built-in mechanical key built in the portable electronic key 12 is used. When the key 12a is attached, the key 12a can be rotated around the rotation axis R. In other cases, the rotation around the rotation axis R is restricted by a predetermined fixing mechanism (not shown). Fixed.

  The knob base 15 described later includes an opening 51 (for example, an opening 51 in FIGS. 5A and 5B described later) that opens toward the key hole 14a of the key cylinder 14, and the operation knob 16 includes the knob base. The knob base 15 is mounted so as to cover the 15 openings 51. The operation knob 16 protrudes from the steering column (not shown) when mounted on the knob base 15 and is rotatable about the rotation axis R.

As shown in FIGS. 3A, 3B, 4A, and 4B, for example, the operation knob 16 includes a grip portion 21 that is gripped by an operator, and the grip portion 21. And an engaging portion 22 provided continuously with the engaging portion 22 and a pressing portion 23 provided integrally with the engaging portion 22.

The recess 52 has two inner wall surfaces 52B that are opposed to each other so as to sandwich the axis from both sides at a position shifted from the axis of the rotation axis R, and are parallel to the attaching / detaching direction P. At one end in the attaching / detaching direction P, a notch 54 is formed by notching the wall 53 of the recess 52.
Further, a concave groove 55 extending in the attaching / detaching direction P is formed on each inner wall surface 52B. A locking groove 56 is formed on the bottom surface 55 </ b> A of one of the two recessed grooves 55.

  For example, as shown in FIGS. 3B and 5A, the engaging portion 22 of the operation knob 16 has a rotation axis on the lower surface 21B of the gripping portion 21 whose vertical direction is the axial direction of the rotation axis R. There are provided two ridges 41 that protrude at positions deviated from the R axis, face each other so as to sandwich the axis from both sides, and extend in the attaching / detaching direction P. Each protruding portion 41 has an outer side surface 41A opposite to the axis side of the rotation axis R (that is, externally in the short direction of the grip portion 21 having a substantially rectangular shape when viewed from the axial direction of the rotation axis R). A convex portion 42 that protrudes from above and extends in the attaching / detaching direction P is formed. And the press part 23 extended in the attachment / detachment direction P is integrally connected to the one ends 41a and 42a of the attachment / detachment direction P of one protrusion part 41 and the protrusion part 42 among each two protrusion parts 41 and the protrusion part 42.
