(57) A guide hole (22a) of an operation portion (22) of an operation body (20) is inserted
with a tactile pin (23) having, at a top end, an abutting-end portion (23a) abutting
an abutting-target surface of a cam (12) in a casing (11). When a lever (21) of the
operation body (20) is operated to change a position of a top end portion of the operation
portion (22), the abutting-end portion (23a) slides on the abutting-target surface.
The tactile pin (23) has, on an outer peripheral surface, a first inclined surface
(pin outer periphery inclined surface (23b)). The guide hole (22a) has, on an inner
peripheral surface, at a position facing the first inclined surface, a second inclined
surface (guide hole inner periphery inclined surface (22b)). Normal directions of
the first inclined surfaces (23b, 23f, 23g) and second inclined surfaces (22b, 22f,
22g) are inclined with respect to operation directions of the lever (21). The tactile
pin (23) is biased in the guide hole (22a) so that the first and second inclined surfaces
abut each other.
